is-absolute

What is is-absolute?

The is-absolute npm package is a utility that helps determine if a given file path is an absolute path. This can be particularly useful in file system operations where the distinction between absolute and relative paths is important.

What are is-absolute's main functionalities?

Check if a path is absolute

This feature allows you to check if a given path is absolute. An absolute path is one that starts from the root directory, as opposed to a relative path which is relative to the current working directory.

const isAbsolute = require('is-absolute');

console.log(isAbsolute('/home/user')); // true
console.log(isAbsolute('home/user')); // false
