Find the shortest string in array

Question

How can i find the shortest string in javascript array with different count of array elements? I used

var min = Math.min(arr[0].length,arr[1].length,arr[2]         


        

Answer 1

Use Array#map to create an array of lengths, and then apply it to Math.min():

var arr = ['cats', 'giants', 'daughters', 'ice'];
var min = Math.min.apply(Math, arr.map(function(str) { return str.length; }));
console.log(min);

Or use ES6's array spread and arrow function:

var arr = ['cats', 'giants', 'daughters', 'ice'];
var min = Math.min(...arr.map(({ length }) => length));
console.log(min);
