JavaScript works in Console not in code new Date(parseInt(<datestring>))

Question

can anybody help and tell me why this

new Date(parseInt("1395427364000"))

works in the console but this

var testDate = new Date(parseInt("1395427364000"))

in the code gives me an invalid date

Answer 1

The console prints the return value of a statement. The return value of a var x = someValue statement is not the value. If you later just call testDate in the console, you'll indeed see its value.
