Reverse String in JavaScript

reverseString one-liner

const reverseString = (string) => [...string].reverse().join("");

Summary

• The spread operator [...string] splits the string into an array of individual characters. This is preferred over .split("") because it correctly handles Unicode characters like emojis.
• The .reverse() method reverses the array of characters in place.
• The .join("") method joins the reversed array back into a single string with no separator.
• Chaining these three operations together creates a clean one-liner for reversing any string in JavaScript.
