Why this given below question's answer is 5 ?

Question

var str = "abc";
var arr = [1,2,3];
str.length=2;
arr.length=2;
console.log(str.length + arr.length);

Answer 1

You can change the length of an array value but not the string. Strings are immutable by design. You can't change them.

With “abc” , the length will always remain 3. Then you changed arr length to 2. In total this gives 5.

Answer 2
