Reverse String

Challenge Description​

Given a string, reverse the string and return the result. For example:

  • "hello" becomes "olleh"
  • "apple" becomes "elppa"

Tips to Solve​

tip
  1. Convert the string to an array using the split method.
  2. Reverse the array using the reverse method.
  3. Convert the array back to a string using the join method.

Step-by-Step Solution​

Let's break down the solution into easy steps:

  1. Convert the String to an Array: Use the split method to convert the string into an array of characters.

    const strArray = "hello".split(""); // ["h", "e", "l", "l", "o"]

  2. Reverse the Array: Use the reverse method to reverse the order of the elements in the array.

    const reversedArray = strArray.reverse(); // ["o", "l", "l", "e", "h"]

  3. Convert the Array Back to a String: Use the join method to combine the elements of the array back into a string.

    const reversedString = reversedArray.join(""); // "olleh"

Full Solution Code​

Here is the complete solution using the steps above:

const reverseString = (str) => str.split("").reverse().join("");
console.log(reverseString("hello")); // Output: "olleh"
console.log(reverseString("apple")); // Output: "elppa"
