Remove Last Character | Javascript Substring [Easy Method]

To remove the last character from a string using JavaScript’s substring() method, you can specify the desired range of characters to extract. Here’s an example:

var str = "Hello, World!";
var substring = str.substring(0, str.length - 1);

console.log(substring); // Output: Hello, World

In the above code, str.length - 1 is used as the endIndex parameter for the substring() method. This subtracts 1 from the length of the string, effectively excluding the last character from the extracted substring.

After removing the last character, the resulting substring will be assigned to the substring variable. In this example, the output will be “Hello, World” without the exclamation mark.

Keep in mind that the substring() method doesn’t modify the original string but instead returns a new string. If you need to remove the last character from the original string permanently, you can reassign the modified substring back to the original variable, like this:

str = str.substring(0, str.length - 1);
