Please help

Question

Can somebody please break this down for me, what the mathematical process is of the following
var x = “2*2”
var y= 4
var z = eval(x+y)
alert(z)

Answer 1

// Because you make the 1st variable with a string and he can not make the operation.
But if you use int, JavaScript can make the operation as a calculator.

Answer 2

hi Luke Sandford
ok so x is a string value
then y is an int value
z evaluates to a string because it is the first value so the output is 2*24
i hope this helps
