In this article, we will show you how to reverse each word of a sentence in JavaScript.

Code Snippet to reverse each word in a string

Here’s an example code snippet in JavaScript that demonstrates how to reverse each word in a string:

function reverseWords(str) {
  // Split the string into an array of words
  const words = str.split(' ');

  // Reverse each word in the array
  const reversedWords = words.map(word => {
    return word.split('').reverse().join('');
  });

  // Join the reversed words back into a string
  const reversedString = reversedWords.join(' ');

  return reversedString;
}

// Example usage
const sentence = "Hello, World! This is a sample string.";
const reversedSentence = reverseWords(sentence);
console.log(reversedSentence);

Output: “olleH, dlroW! sihT si a elpmas gnirts.”

In the reverseWords function, we split the input string into an array of words using the split method. Then, we use the map method to iterate over each word and reverse its characters by splitting, reversing, and joining them back together. Finally, we join the reversed words back into a string using the join method and return the result.

You can pass any string to the reverseWords function and it will reverse each word in the sentence, maintaining the original word order.
