Module 1: JavaScript ES6+ Fundamentals
Before tackling React, it is essential to master modern JavaScript (ES6+). This module covers the features you will use daily.
Why This Module?
As a PHP developer, you already know programming. However, modern JavaScript (since ES6/2015) introduces concepts and syntaxes that differ significantly from PHP.
React heavily uses these features. Without mastering them, React code will seem cryptic to you.
Chapters
| # | Chapter | Content | |
|---|---|---|---|
| 1 | Variables and Scope | const, let, destructuring, spread operator |
|
| 2 | Functions | Arrow functions, default parameters, callbacks | |
| 3 | Asynchronous | Promises, async/await, error handling | |
| 4 | ES6 Modules | import/export, code organization |
Module Objectives
By the end of this module, you will be able to:
- Declare variables with
constandlet - Use destructuring to extract values
- Write arrow functions
- Handle asynchronous code with async/await
- Organize your code into modules
Quick Comparison PHP vs JavaScript
| Concept | PHP | JavaScript ES6+ |
|---|---|---|
| Constant variable | const X = 1; |
const x = 1; |
| Modifiable variable | $x = 1; |
let x = 1; |
| Associative array | ['a' => 1] |
{ a: 1 } (object) |
| Anonymous function | function($x) { } |
(x) => { } |
| Interpolation | "Hello $name" |
`Hello ${name}` |
| Null coalescing | $x ?? 'default' |
x ?? 'default' |
Estimated Time
Approximately 2-3 hours to go through this module and complete the exercises.
