Creating a Module

Share This Post

In JavaScript, we can use modules to organize our classes so our code is more manageable. We can put as many classes as we want into a module. Each module is its own JavaScript file. Typically, the functionality related to that module is put into the file and organized accordingly…in classes, objects, etc.

Imagine if we have a JS file with the Animal class…

class Animal { 
    constructor(name){
        this.name = name;
    }
    speak(){
         return ${this.name} says;
    }
}

The way it gets used by other JS is by using the “export” keyword.

export class Animal {
     constructor(name){
        this.name  = name;
    }
    speak(){
         return ${this.name} says;
    }
}

Tada! We have created an JavaScript module. The way we use it is by importing it into another file.

Happy Coding!
