Extending Number.prototype in javascript and the Math object?

Question

I\'ve always wondered why Javascript has the global Math object instead of giving numbers their own methods. Is there a good reason for it?

Also are there any drawbacks

Answer 1

So, the conversation on whether its a good idea or not aside, you can do this fine.

You can do 123.x() but the interpreter for js is broken (as it doesn't interpret the dot as a message dispatch)

Weirdly, you can use 123 .x() (with a space between the number and the dot) instead, and it'll work.

123..also works but that's because you've effectively made a decimal and then dispatching to it

(typeof 123.) === 'number') // true

Try:

Number.prototype.times = function(other) { return this * other }; 3 .times(5);

in the console.
