Filter array by string length in javascript [duplicate]

Answer 1

You can filter it

var array_cleaned = array_1.filter(function(x) {
    return x.length > 3;
});

Answer 2

If you don't want to use the filter function, this works just fine I think.

arrayClean = [];
for(int i = 0; i<array1.length; i++) {
     if(array1[i].length < 3) {
          arrayClean[i] = array[i];
     }
}

Answer 3

You can use filter method:

var array_1 = ["the","quick","brown","fox","jumped","over","the","lazy","dog"];
var array_cleaned = array_1.filter( function( element ) {
  return element.length > 3;
});
console.log(array_cleaned); //["quick", "brown", "jumped", "over", "lazy"]
