Does developer used to be memorize every single tags, keyword, function, etc?

Question

Until now, i'm still thinking about that. I mean, highly possibilities that developer'll forget some keywords. Especially if they learn multi-programminglanguange. Even if they front end, or developer in general. Will they use something like predefined script (copy paste from what already made before) or they used sheet of keywords or even refering to coding documentation (including every elements, tag, keyword, class, function, etc) ?

Answer 1

it becomes like a spoken language after awhile. but I believe even the best uses references occasionally. such things as Google are very helpful

Answer 2

Instead of memorize, you should practice write codes on every single tags, keywords, functions, etc.....
