10 JavaScript Terms You Should Know

From currying to closures there are quite a number of special words used in JavaScript. These will not only help you increase your vocabulary but also better understand JavaScript. Special terms are normally found in documentation and technical articles. But some of them like closures are pretty standard things to know about. Knowing what the word itself means can help you know the concept it's named for better.

1. Arity
2. Anonymous
3. Closure
4. Currying
5. Hoisting
6. Mutation

Pure functions

A pure function for given the same input will always return the same output and evaluation of this function will not cause any side effects.

Advantages of using pure functions:

• easy to test, as they always return the same value,
• easy to debug, as they shouldn't cause any race conditions and circular dependencies,
• simple and independent, as they don't cause any side effects (it makes design clean),
• easy to scale application up, as they shouldn't rely on machine state.

I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

A lot of people mentioned other immutable JS libraries after reading my post. I thought it would be good to make a list of available ones.

There are two types of immutable libraries: simple helpers for copying JavaScript objects, and actual persistent data structure implementations. My post generally analyzed the tradeoffs between both kinds of libraries and everything applies to the below libraries in either category.

Libraries are sorted by github popularity.

Persistent Data Structures w/structural sharing
