What's Closure in JavaScript?
The same way that a function can return a string, object, array, or integer, a function can also return another function. Again, this is because functions are first class objects in JavaScript just like any other object.
According to the MDN Article on Closures, a closure is the combination of a function and the lexical environment within which that function was declared.
From You Don't Know JS, "a closure is when a function is able to remember and access its lexical scope even when that function is executing outside its lexical scope."
Hope this is helpful, give me a thumbs up if it does :)
