Legth of element on array

Question

Hello, coders.
How can i find the length of each element of array?
Example :
var thisArray = "Cake", "chocolate";
//return 4, 9 ;

Thank you in advance.

Answer 1

var arr = ["Cake", "Chocolate"];
var len = new Array();
function getLen(el){
for(i=0; i<el.length; i++)
len.push(el[i].length)
return len.join(",")
}

alert(getLen(arr)) // return 4,9

getLen() returns a string with the length of all your words in the array passed as argument.
