Should I ignore annoying warnings?

Question

Adobe Dreamweaver

After other editors, I'm at a loss what these "use strict" mean, then it's about triples anyway. I checked it in Opera, Chrome, and even IE - everything works like clockwork. Ignore?

Answer 1

It's not about Dreamweaver, it's about common JS practice. Strict comparison (===) is usually used for comparison. This ensures that the left and right sides will have a value with the same data type. It will work with a non-strict comparison (==), but interesting errors are possible
