Delete First Character of String If It Is 0

Delete first character of string if it is 0

When working with JavaScript, you may come across situations where you need to delete the first character of a string if it is 0. In this blog post, we will explore two different solutions to achieve this.

Solution 1: Using the slice() method

The first solution involves using the slice() method to remove the first character of the string if it is 0. The slice() method returns a new string containing a portion of the original string, starting from the specified index.

Here’s the code snippet:

const str = "012345";
const newStr = str.slice(str[0] === "0" ? 1 : 0);

console.log(newStr); // Output: "12345"

In this code, we check if the first character of the string is “0” using the conditional (ternary) operator. If it is, we use the slice() method to create a new string starting from the second character. Otherwise, we create a new string starting from the first character.

Solution 2: Using the substring() method

The second solution involves using the substring() method to achieve the same result. The substring() method returns the part of the string between the start and end indexes.

Here’s the code snippet:

const str = "012345";
const newStr = str.substring(str[0] === "0" ? 1 : 0);

console.log(newStr); // Output: "12345"

Similar to the previous solution, we check if the first character of the string is “0” using the conditional (ternary) operator. If it is, we use the substring() method to create a new string starting from the second character. Otherwise, we create a new string starting from the first character.

Both solutions achieve the same result, so you can choose the one that you find more suitable for your specific use case.

That’s it! You now have two different solutions to delete the first character of a string if it is 0 in JavaScript. Feel free to use the code snippets provided in your own projects.
