JavaScript Arrays Convert a String to an Array
Example
The .split() method splits a string into an array of substrings. By default .split() will break the string into substrings on spaces (" "), which is equivalent to calling .split(" ").
The parameter passed to .split() specifies the character, or the regular expression, to use for splitting the string.
To split a string into an array call .split with an empty string (""). Important Note: This only works if all of your characters fit in the Unicode lower range characters, which covers most English and most European languages. For languages that require 3 and 4 byte unicode characters, slice("") will separate them.
var strArray = "StackOverflow".split("");
// strArray = ["S", "t", "a", "c", "k", "O", "v", "e", "r", "f", "l", "o", "w"]
6
Using the spread operator (...), to convert a string into an array.
var strArray = [..."sky is blue"];
// strArray = ["s", "k", "y", " ", "i", "s", " ", "b", "l", "u", "e"]
