Trimming the Last Character from a String in JavaScript

In certain scenarios, you may encounter the need to remove the last character from a string. JavaScript offers several methods to achieve this.

One efficient solution is to utilize the substring() function. This method allows you to extract a portion of a string based on the specified indices. By providing the correct parameters, you can exclude the last character.

For instance, let's consider the string "12345.00". To trim the last character (which is 0), we can use the following code:

<code class="javascript">let str = "12345.00";
str = str.substring(0, str.length - 1);
console.log(str);</code>

This will output "12345.0", as the last character has been removed.

The key to using substring() effectively is to specify the correct indices. In this case, providing 0 as the starting index includes the first character, and specifying str.length - 1 as the ending index excludes the last character.
