How to Check if a String Ends with a Specific Character in JavaScript 🤔✅

So, you want to find out if a string ends with a particular character in JavaScript? We've got you covered! In this guide, we'll explore different approaches to solve this problem and provide you with easy solutions. Let's dive in! 💪🚀

Option 1: Using the endsWith() Method 🙌

You might be tempted to search for an endsWith() method in JavaScript, just like there is a startsWith() method. However, there is no built-in endsWith() method available in JavaScript. But don't worry! We have other options. 😉

Option 2: Check the Last Character of the String 👌

A simple solution is to take the length of the string and check the last character. Let's use your example string, where we want to check if it ends with #:

var str = "mystring#";
var lastCharacter = str[str.length - 1];

if (lastCharacter === "#") {
  console.log("The string ends with #");
} else {
  console.log("The string does not end with #");
}

In this example, we access the last character of the string using the index str.length - 1 and compare it to #. If they match, we conclude that the string ends with #. Otherwise, it doesn't.

Option 3: Regular Expressions 🧐

Another powerful way to check if a string ends with a specific character is by using regular expressions. Regular expressions provide a flexible and concise way to search for patterns within strings.

Here's how you can use a regular expression to check if a string ends with #:

var str = "mystring#";
var endsWithHash = /#$/.test(str);

if (endsWithHash) {
  console.log("The string ends with #");
} else {
  console.log("The string does not end with #");
}

In this example, the regular expression /#$/ matches any string that ends with #. The test() method checks if the given string matches the regular expression.

Which Option is the Best? 🏆

Both Option 2 (checking the last character) and Option 3 (using regular expressions) are valid approaches. The best option depends on your specific use case and preferences.

If you expect to check the ending character frequently, Option 3 might be more efficient due to the flexibility of regular expressions. On the other hand, if you only need to check the ending character occasionally, Option 2 provides a simple and straightforward solution.

Conclusion ✨

Checking if a string ends with a specific character in JavaScript may seem like a daunting task, but with the right techniques, it becomes a breeze 🌬️💨. In this guide, we explored different approaches, including checking the last character and using regular expressions.

Now, you have the knowledge to tackle this problem with confidence! Choose the option that suits your needs and get ready to conquer those string endings like a JavaScript ninja! 💪🥷
