Naming A Variable Dynamically?

I have an array with the values: 1, 4, 7, 8, 2
I want to loop through the array and dynamically name a variable to append the array elemnt to the variable name something like this:
i = 0
while (myArray.length){
var myVar + myArray[i] = "my variable name is called:" + myVar + myArray[i]
i++
}

but i cant name the variable dynamically. Do I have to do something like: String(var "myVar" + myArray[i]) or something?
