Cutting off number at each digit to construct an array in JavaScript

Problem

We are required to write a JavaScript function that takes in a number. Our function should return an array of strings containing the number cut off at each digit.

Example

Following is the code −

 Live Demo

const num = 246; const cutOffEach = (num = 1) => {    const str = String(num);    const res = [];    let temp = '';    for(let i = 0; i < str.length; i++){       const el = str[i];       temp += el;       res.push(temp);    };    return res; }; console.log(cutOffEach(num));

Output

Following is the console output −

[ '2', '24', '246' ]
