Having a solid grasp of web development frameworks and libraries is crucial to understanding programming and script languages.
In this article, you’ll learn:
- The concepts and techniques you need to know
- Why React is important
- How long it takes to learn
Why React is Important
As a front-end web developer, you will build several user interfaces for different projects. UI refers to on-screen menus, search bars, buttons, and anything else people interact with to use an application or website.
Every successful developer uses the right tools to make development projects easier and more efficient. With React JS, you’ll build more efficient user interfaces.
What to Learn Before Covering React
There are specific concepts you need to understand before going into React. Here are the topics you should learn to better understand React:
- Async Await: Async-await provides a more straightforward way to interact with promises. They make asynchronous code look synchronous, and yet, the work is still asynchronous.
- Modules, import, export: When working with React, you isolate your components on separate files. You export some elements from a file and import them to another.
- Inheritance: This allows you to create a class that inherits all the functionality of its parent class, and add extra features.
- Typecasting: Typecasting, also known as coercion, is the conversion of a data type to another data type.
- Constructor function: This allows you to do the necessary custom initialization on an instantiated object.
- Undefined and Null: Undefined is a variable declared without any value assigned, while null is an assignment value.
- Array functions: This enables you to perform multiple calculations on several items in an array.
- Block-level scoping: The block scope restricts the outside of a specific block from accessing the variable declared inside the block.
- The “this” keyword and its binding rules: “This” keyword is an object executing the current piece of code or function.
- Arrow functions: This introduces concise body syntax to let you create functions in a cleaner way than the regular functions.
- String manipulation: This involves the different processes of handling, analyzing, and modifying strings.
- Event bubbling and capturing: Event bubbling is when you propagate an event from a child element to ancestor elements in the DOM while event capturing is the propagation of an event from ancestor elements to a child element.
Why is React Hard to Learn?
Another reason is learning everything at once. This is a common mistake made by upcoming web developers/programmers. Most learning resources on the internet tend to cram in many topics and when you try to learn all at once, it can be difficult to fully grasp the concepts.
So, learn one thing at a time. Learn at your own pace and practice what you learn by writing code for real-life projects.
How Much Time Does it Take to Learn React?
After gaining a solid grasp of the necessary topics mentioned above, you should be able to learn the basics of React within one to two months. If you keep studying and working with this JS library, you should be able to create interactive front-end for websites and apps in four to six months.
However, the time it’ll take you to learn React will be determined by your availability, dedication, and learning material.
So, someone who studies full-time will learn it faster than someone who studies part-time. The learning resources you use — Techdegree, video courses, and text-based courses — will determine how fast and efficient you’ll learn.
We recommend focusing on the client-side development skills and some other JS-relevant techniques such as:
