Given a string representation of a number, how can I convert it to number type in TypeScript?

var numberString: string = "1234";
var numberValue: number = /* what should I do with `numberString`? */;

You can use the parseInt or parseFloat functions, or simply use the unary + operator:

var x = "32";
var y: number = +x;
