You example is not clear enough, but I guess that your problem is because of Typescript inference:

var x = 3; // x is a number
x = "45";  // compiler error

But, if you do:

var x : any = 3; // x can be anything
x = "45";

Or:

var x; // x is any forever
x = '45';  // x is still any

You can find further details on those great slides and on docs
