In JavaScript, all functions are first class functions.

https://abs.twimg.com/emoji/v2/... draggable="false" alt="4โฃ" title="Tastenkappe Ziffer 4" aria-label="Emoji: Tastenkappe Ziffer 4">The functions that take a function as an argument, or return a function as a return value are called ๐๐ถ๐ด๐ต๐ฒ๐ฟ-๐ผ๐ฟ๐ฑ๐ฒ๐ฟ ๐ณ๐๐ป๐ฐ๐๐ถ๐ผ๐ป๐.

It does this without mutating the original array.

https://abs.twimg.com/emoji/v2/... draggable="false" alt="7โฃ" title="Tastenkappe Ziffer 7" aria-label="Emoji: Tastenkappe Ziffer 7">๐ณ๐ถ๐น๐๐ฒ๐ฟ() calls a function on each element of an array and returns a new array containing only the elements for which that function returns true. In other words, it filters the array, based on the function passed to it.

You can solve almost any array processing problem using the reduce method.

It takes an argument for the delimiter, which can be a character to use to break up the string or a regular expression.

It takes an argument for the delimiter that is used to separate the array elements in the string.
