Find the shortest string in an array - JavaScript

We are required to write a JavaScript function that takes in an array of strings and returns the index of string that is shortest in length.

We will simply use a for loop and persist the index of string which is shortest in length.

Example

Following is the code −

const arr = ['this', 'can', 'be', 'some', 'random', 'sentence']; const findSmallest = arr => {    const creds = arr.reduce((acc, val, index) => {       let { ind, len } = acc;       if(val.length < len){          len = val.length;          ind = index;       };       return { ind, len };    }, {       ind: -1,       len: Infinity    });    return arr[creds['ind']]; }; console.log(findSmallest(arr));

Output

This will produce the following output in console −
