Writing great JavaScript
I probably could have named this post something like “Writing clean, validating and portable JavaScriptâ€, but that would be no where near as catchy. The problem with “great†is it means different things to different people. I am going to show you my idea of great which may differ from many developers views, but I hope it helps someone improve their code. So what’s the point in this, why can’t you just carry on writing JavaScript as you have been for a...

Can a == true && a == false be true in JavaScript?
JavaScript is a weak typed language and it has a loose comparison feature where two objects/values of different type can be compared using == operator. This provides developers great flexibility and confusion at the same time. Before understanding how == works in JavaScript, can you first answer the question in the post title?
