Use it often.

​@@manojht8036 what if we have other projects to do which doesn't involve some topics we have learnt before. In this case, we would not use it for a while and when we come after finishing that project(sometimes even few minths), we would've forgotten some of what we learnt.😅 What to do in this case?

@@abcdabcd8605 let's understand here a little bit. You're not a robot.. are you ? If you were robot, then I don't need to tell you and you already know how to keep it in your disk. And if you're human .. every human will forget something he read or tried to force it in his brain. You need to connect with something emotionally and mentally to remember it. Like for example if I ask you what happened in some weird date in 2000 .. if you were already born in that time would you be able to answer me ? (If yes, kudos. You've idyllic memory, in that case I didn't have to tell anything), but if I ask you what happened in your last birthday you can easily tell that. Because it was a big day for you. So the way to understand and remember is just to use it more often. It will take years and years until you become perfect. But eventually you will be. Also one more thing. You don't need to remember complete javascript or whatever it is you're trying to learn. You would just basically insult all youtubers and bloggers and whoever else is providing content of that technology..because of that. If you don't remember something try and search it. Contact or research. Do something and get it. Focus your mind on problem solving
