Compare 2 array's elements against each other and return count JavaScript

Question

I have 2 arrays that I need to compare against each other and return the count of the same.

Example: compare array1 [abcd] against array2 [adce]. Return would be 2,1

Answer 1

You get 1 as output because length is not defined in your code

var array1 = ['a','b','c','d'];
var array2 = ['a','d','c','e'];

var length = Math.min(array1.length,array2.length);
var countMatched = 0,countNotMatched = 0;

for(var index=0;index= 0)
    countNotMatched++;
}
alert(countMatched );
alert(countNotMatched);
