How to use typed variables in javascript?

Question

Is there any way to use typed variables in javascript? Like integer, string, float…

Answer

JavaScript variables are not typed.

JavaScript values are, though. The same variable can change (be assigned a new value), for example, from uninitialized to number to boolean to string (not that you’d want to do this!):

var x;       // undefined
x = 0;       // number
x = true;    // boolean
x = "hello"; // string
