Array chaining, filter array by typeof primitive and return shortest length element

Question

My failed attempt to pull out the shortest string from an array filled with different types of primitives. What am I doing wrong? Are there any other wa

var bands = ([30, 'Seconds', 'to', 'Mars', 1, 'Direction', true]);

function tinyString(collection) {
var tinyStr = '';
return collection.
    filter(function (x) {
      return typeof x === 'string' 
    }).
    forEach(function (y) { 
        if (tinyStr > y){
          return tinyStr = y
        } 
    }) 
}

console.log(bands); // --> 'to'

Answer 1

You can sort on length and type, and return the first one

var bands = ([30, 'Seconds', 'to', 'Mars', 1, 'Direction', true]);

function tinyString(collection) {
    return collection.sort((a,b)=>typeof a === 'string' ? a.length-b.length:1).shift();
}

console.log( tinyString(bands) );
