Is it very important to memorize most code I come across or all I need is to know what a specific thing can do

Question

Like If I know what a specific thing can do Is it okay to copy and paste

Answer 1

Basically,you will memorize some really common functions and methods automatically if you use them frequently. Of course,you can't and won't memorize all of them. Otherwise,you won't be asking here as you are already a dictionary. You can choose to memorize those which are useful TO YOU. You can of course use part of the code created by others when you are not familiar with them. However,you have to at least know what they are about,right? Otherwise,you will waste a lot of time. So tlyou should have the feeling like 'Ooh,that thing. I forgot the syntax but I knew it is what I want!'
