// It essentially SPLITS the sentence inserted in the required argument
// into an array of words that make up the sentence.

var input = "How are you doing today?";
var result = input.split(" "); // Code piece by ZioTino

// the following code would return as
// string["How", "are", "you", "doing", "todaY"];
