javascript-lodashHow do I use Lodash's join function in JavaScript?

Lodash's join function is used to join the elements of an array into a string. It takes two arguments, the array to join and an optional separator string. It returns a string of the joined elements.

Example

const _ = require('lodash');

const arr = ['a', 'b', 'c'];
const sep = '-';

const joined = _.join(arr, sep);

console.log(joined);

Output example

a-b-c

The code above uses Lodash's join function to join the elements of an array arr with a separator sep and logs the result to the console.

Code explanation

• const _ = require('lodash');: imports Lodash library
• const arr = ['a', 'b', 'c'];: creates an array with elements a, b, c
• const sep = '-';: creates a separator string -
• const joined = _.join(arr, sep);: calls Lodash's join function with arguments arr and sep
• console.log(joined);: logs the result of _.join to the console
