    JavaScript Import Code Blocks

    In the last challenge, you learned about export default and its uses. To import a default export, you need to use a different import syntax. In the following example, add is the default export of the math_functions.js file. Here is how to import it: The syntax differs in one key place. The imported value, add, is not surrounded by curly braces ({}). add here is simply a variable name for whatever the default export of the math_functions.js file is. You can use any name here when importing a default.

    JavaScript Export Code Blocks

    Create an Export Fallback with export default In the export lesson, you learned about the syntax referred to as a named export. This allowed you to make multiple functions and variables available for use in other files. There is another export syntax you need to know, known as export default. Usually you will use this syntax if only one value is being exported from a file. It is also used to create a fallback value for a file or module. Below are examples using export default: The first is a named function, and the second is an anonymous function. Since export default is used to declare a fallback value for a module or file, you can only have one…

    JavaScript Modules

    Create a Module Script JavaScript started with a small role to play on an otherwise mostly HTML web. Today, it’s huge, and some websites are built almost entirely with JavaScript. In order to make JavaScript more modular, clean, and maintainable; ES6 introduced a way to easily share code among JavaScript files. This involves exporting parts of a file for use in one or more other files, and importing the parts you need, where you need them. In order to take advantage of this functionality, you need to create a script in your HTML document with a type of module. Here’s an example: A script that uses this module type can now use the import and export features you will…
