Find the Smallest element from a string array in 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.
Therefore, let’s write the code for this function −
Example
The code for this will be −
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
The output in the console will be −
