When working with JavaScript modules, understanding how to specify paths for imports is crucial for organizing your code effectively. In this guide, we’ll explore module specifiers and how to use them to import modules in your projects.

What are Module Specifiers?

Module specifiers are strings used to specify the location of a module that you want to import. They provide information on where to find the module relative to the current file or using absolute paths.

Relative Paths

Relative paths are one way to specify the location of a module relative to the current file. You can use ./ to indicate the current directory and ../ to navigate up one directory level. Let's look at an example:

// main.js
import { greet } from './utils/greetings.js';

In this example, we’re importing the greet function from a module located in the utils directory relative to the current file.

Absolute Paths

Absolute paths provide the full path to the module, starting from the root directory of the project. This can be useful for…
