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(o => o.length));

console.log(min);
