JS from Scratch #35 | ES6 Modules: What is the difference between Named export and Default export?
How to properly split code into independent files, why you shouldn't mix CommonJS and ES6 modules, and how to liven up your interface with function imports? We'll explore the JavaScript module system.
⠀
🔹 IN THIS VIDEO:
We move from the theory of code isolation to pure practice and take a detailed look at the native ECMAScript module system (ES6 Modules). You'll learn how to properly link files together, intuitively group functions, and use VS Code's autocompletion for quick imports.
⠀
🔹 GOLDEN RULES FOR WORKING WITH MODULES:
No mixing: In modern web development, there are two standards: CommonJS (CJS) and ES6 Modules (GSM). You'll learn why it's strictly forbidden to use them simultaneously in the same project.
HTML Attribute: We'll explore why it's critical to specify the type="module" attribute when including the main script in an HTML file, and how this changes browser behavior.
Path Specifics: You'll see why, when working without bundlers (using vanilla JS), it's essential to include the full file extension in paths (e.g., from './rotate.js'), even if bundlers will allow you to ignore it in the future.
⠀
🔹 PRACTICE: NAMED VS DEFAULT EXPORT:
We'll implement an interactive interface for controlling emoji animations (rotation, start, and pause) and examine the two main methods of exporting code:
Named Export: When we export specific functions, variables, or objects under their own names.
Default Export: We'll examine the syntax of export default, learn why there can only be one default export per file, and how this simplifies importing auxiliary modules (for example, our rotate function). ⠀
