How do you mean? You can't type a word without using it in a word processor. Once the word is typed out it's been used. Variables need to be declared then used so 2 separate steps.
There's no direct equivalent but word like won't bother me about spelling or grammar until I'm done typing that part
What do you mean? Variables do not necessarily need to be used, you can allocate memory for some value and initialise it but then simply don't do anything with it.
You can but compilers will optimise that away unless you tell it not to.
Meanwhile go: you will remove it or I won't compile, unless you know the secret handshake
Yes you can but the little red squiggles show in your editor to warn you that it's unused code. That's what the whole post is about lol
