I just don't get it


I have been trying to use javascript on other sources to see if it would work. But I would just get errors when i run it. I am looking at a lot of examples and see a lot of <> with something in-between before the coding etc… So here are my questions.

What does<> mean and why do i need it?
Am i required to know any other language to get javascript to run?
Where can I solely use Javascript?

Any help at all will relief my frustration, so thanks for your service
