Question

I am practicing this https://developer.mozilla.org/en/Canvas_tutorial/Basic_animations Clock tutorial.
Everything in the code is clear to me.
Accept this hr = hr>=12 ? hr-12 : hr; is not clear me. May be it’s a if else statement.

Can any explain what this code is doing?

Thanks 🙂

Answer 1

This is the ternary operator (?:)
Here is the simple explanation of what is being done here:

if(hr>=12)
{
    hr=hr-12;
}
//or else hr will have its same value
