is there way compare 2 arrays , return new array indicating values matched?

for example

a = ['africa', 'america', 'europe'] b = ['africa', 'asia', 'europe']  // need // c = [true, false, true] 

edit: far have

function mask(arr1, arr2) {   var arr = [];   (var = 0; < arr1.length; i++) {      arr.push(arr1[i] === arr2[i]);   }   return arr; } 

just loop through array. example:

var = ['africa', 'america', 'europe']; var b = ['africa', 'asia', 'europe'];  var index = 0; var c = []; while(a.length > index){   c.push(a[index] === b[index]);   index++ }
