An react js tutorial pdf free download to React How to use create-react-app. Developed at Facebook and released to the world init drives some of the most widely used apps, powering Facebook and Instagram among countless other applications.
Its primary goal is to make it easy to reason about an interface and its state at any point in time, by dividing the UI into a collection of components.
At the time when React was announced, Ember. js and Angular 1. x were the predominant choices as a framework. Both these imposed so react js tutorial pdf free download conventions on the code that porting an existing app was not convenient at all. Also, those 2 frameworks brought too much to the table, while React only chose to implement the View layer instead of the full MVC stack. At the time, Angular 2. x was announced by Google, along with the backwards incompatibility and major changes it was going to bring.
Moving from Angular 1 to 2 was like moving to a different framework, so this, along with execution speed improvements that React promised, made it something developers were eager to try. Being backed by Facebook is, of course, going to benefit a project if react js tutorial pdf free download turns out to be successful.
Facebook currently has a strong interest in React, sees the value of it being Open Source, and this is a huge plus for all the developers using it in their own projects, react js tutorial pdf free download. Even though I said that React is simpler than alternative frameworks, diving into React is still complicated, but mostly because of the corollary technologies that can be integrated with React, like Redux and GraphQL.
React in itself has a very small API, and you basically need to understand 4 concepts to get started:. React is a library, so saying install might sound a bit weird.
Maybe setup is a better word, react js tutorial pdf free download, but you get the concept. The simplest one is to add the React JavaScript file into the page directly. This is best when your React app will interact with the elements present on a single page, and not actually controls the whole navigation aspect. Here we loaded both React and React DOM. Why 2 libraries?
Hence the need for React DOM, to add the wrappers for the browser. After those tags you can load your JavaScript files that use React, or even inline JavaScript in a script tag:. Starting in this way with script tags is good for building prototypes and enables a quick start without having to set up a complex workflow.
create-react-app is a project aimed at getting you up to speed with React in no time, and any React app that needs to outgrow a single page will find that create-react-app meets that need. You start by using npxwhich is an easy way to download and execute Node. js commands without installing them. npx comes with npm since version 5. org npm is installed with Node. If you are unsure which version of npm you have, run npm -v to check if you need to update.
This is great because you will never have an outdated version on your system, and every time you run it, you're getting the latest and greatest code available. create-react-app created a files structure in the folder you told todolist in this caseand initialized a Git repository.
It also added a few commands in the package, react js tutorial pdf free download. json file, so you can immediately start the app by going into the folder and run npm start. Ejecting is the act of deciding that create-react-app has done enough for you, but you want to do more than what it allows. Since create-react-app is a set of common denominator conventions and a limited amount of options, it's probable that at some point your needs will demand something unique that outgrows the capabilities of create-react-app.
When you eject, react js tutorial pdf free download, you lose the ability of automatic updates but you gain more flexibility in the Babel and Webpack configuration.
When you eject the action is irreversible. You will get 2 new folders in your application directory, config and scripts.
Those contain the configurations - and now you can start editing them. If you are willing to learn React, you first need to have a few things under your belt. React js tutorial pdf free download variable is a literal assigned to an identifier, so you can reference and use it react js tutorial pdf free download in the program. Variables in JavaScript do not have any type attached. Once you assign a specific literal type to a variable, you can later reassign the variable to host any other type, without type errors or any issue.
A variable must be declared before you can use it. There are 3 ways to do this, using varlet or constand those 3 ways differ in how you can interact with the variable later on. If you forget to add var you will be assigning a value to an undeclared variable, and the results might vary.
In modern environments, with strict mode enabled, you will get an error. In older environments or with strict mode disabled this will simply initialize the variable and assign it to the global object. A variable initialized with var outside of any function is assigned to the global object, has a global scope and is visible everywhere. A variable initialized with var inside a function is assigned to that function, it's local and is visible only inside it, just like a function parameter.
Any variable defined in a function with the same name as a global variable takes precedence over the global variable, shadowing it. A new scope is only created when a function is created, because var does not have block scope, but function scope. Inside a function, any variable defined in it is visible throughout all the function code, even if the variable is declared at the end of the function it can still be referenced in the beginning, because JavaScript before executing the code actually moves all variables on top something that is called hoisting.
To avoid confusion, always declare variables at the beginning of a function. let is a new feature introduced in ES and it's essentially a block scoped version of var. Its scope is limited to the block, statement or expression where it's defined, and all the contained inner blocks. Modern JavaScript developers might choose to only use let and completely discard the use of var. Defining let outside of any function - contrary to var - does not create a global variable.
Variables declared with var or let can be changed later on in the program, and reassigned. Once a const is initialized, its value can never be changed again, and it can't be reassigned to a different value. We can however mutate a if it's an object that provides methods that mutate its contents. const does not provide immutability, just makes sure that the reference can't be changed. Modern JavaScript developers might choose to always use const for variables that don't need to be reassigned later in the program.
Because we should always use the simplest construct available to avoid making errors down the road. In my opinion this change was so welcoming that you now rarely see the usage of the function keyword in modern codebases. If the function body contains just a single statement, you can omit the brackets and write all on a single line:. Thanks to this short syntax, arrow functions encourage the use of small functions. Arrow functions allow you to have an implicit return: values are returned without having to use the return keyword.
Another example, when returning an object, remember to wrap the curly brackets in parentheses to avoid it being considered the wrapping function body brackets:. this is a concept that can be complicated to grasp, react js tutorial pdf free download, as it varies a lot depending on the context and also varies depending on the mode of JavaScript strict mode or not. When defined as a method of an object, in a regular function this refers to the object, so you can do:.
The this scope with arrow functions is inherited from the execution context. An arrow function does not bind this at all, so its value will be looked up in the call stack, so in this code car. fullName will not work, and will return the string "undefined undefined" :. Arrow functions cannot be used as constructors either, when instantiating an object will raise a TypeError.
This is where regular functions should be used instead, when dynamic context is not needed. This is also a problem when handling events. DOM Event listeners set this to be the target element, and if you rely on this in an event react js tutorial pdf free download, a regular function is necessary:. This operator has some pretty useful applications. The most important one is the ability to use an array as function argument in react js tutorial pdf free download very simple way:.
in the past you could do this using f. apply null, a but that's not as nice and readable, react js tutorial pdf free download. The rest element is useful when working with array destructuring :. Spread properties allow to create a new object by combining the properties of the object passed after the spread operator:. Given react js tutorial pdf free download object, using the destructuring syntax you can extract just some values and put them into named variables:.
This statement creates 3 new variables by getting the items with index 0, 1, 4 from the array a :. The syntax at a first glance is very simple, just use backticks instead of single or double quotes:.
They are unique because they provide a lot of features that normal strings built with quotes do not, in particular:. an easy way to fix this problem is by having an empty first line, and appending the trim method right after the closing backtick, which will eliminate any space before the first character:.
JavaScript has a quite uncommon way to implement inheritance: prototypical inheritance, react js tutorial pdf free download. People coming from Java or Python or other languages had a hard time understanding the intricacies of react js tutorial pdf free download inheritance, so the ECMAScript committee decided to sprinkle syntactic sugar on top of prototypical inheritance so that it resembles how class-based inheritance works in other popular implementations.
This is important: JavaScript under the hood is still the same, and you can access an object prototype in the usual way.
