// In JavaScript, whether to use `require` or `import` depends on the module system you are using. JavaScript has two main module systems: CommonJS and ES6 (ECMAScript 6) modules. 

// 1. CommonJS (`require`):
//    - CommonJS is the module system traditionally used in server-side JavaScript (Node.js) and is also supported in some older front-end development tools.
//    - To use `require`, you typically write code like this:
   
//    const myModule = require('./myModule');

//    You can use `module.exports` to export values from a module:

//    module.exports = {
//      someFunction: function() {
//        // ...
//      },
//      someValue: 42
//    };


//    To import modules in CommonJS, you use `require()`:
   

//    const myModule = require('./myModule');
//    myModule.someFunction();
//    console.log(myModule.someValue);


// 2. ES6 (`import`):

//  ES6 modules are the standard module system for modern JavaScript both in the browser and with Node.js (though Node.js also supports CommonJS).

//     To use `import`, you typically write code like this:

//    import myModule from './myModule';


//     You can use the `export` keyword to export values from a module:

//    export function someFunction() {
//      // ...
//    }
//    export const someValue = 42;

//    To import modules in ES6, you use `import`:

//    import { someFunction, someValue } from './myModule';
//    someFunction();
//    console.log(someValue);


// In modern JavaScript development, it's generally recommended to use ES6 modules (`import` and `export`) because they provide a more standardized and expressive way to work with modules. However, if you're working with older codebases or specific environments like Node.js, you may still encounter CommonJS (`require`) modules.
