All good software engineers learn this. Unless you’re actively working in some languages, you don’t need to worry about syntax (that’s why reference manuals are there for). Instead, grow your capacity to solve problems and to define precise solutions. Most time is spent doing that, realizing you don’t have a precise idea of what you’re working on and doing research about it. Writing code is just translating that.

But there are other concerns to code that you ought to pay attention to. Will it works in all cases? Will it run efficiently? Will it be easily understood by someone else? Will it easily be adapted to fit to a change of requirements?
