Hey Rahul, I mentioned that in the post but what does this actually help with? I understand hoisting (I believe) but surely decently written code wouldn't rely on hoisting anyways?
I'm a Systems Reliability and DevOps engineer for Netdata Inc. When not working, I enjoy studying linguistics and history, playing video games, and cooking all kinds of international cuisine.
Most code doesn't need to rely on it, but it's not unusual to see code that does.
The simplest example of it's usefulness is that it lets you sort your functions by name instead of by what each of them depends on, which is helpful for finding code quickly.
It also lets you do cyclical recursion (that is, two or more functions that from a recursive loop), which is impossible without some form of hoisting, forward-declaration, or multi-pass parsing.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
hoisting will happen only for named function, not for variable function
