JavaScript- Remove Last Characters from JS String

These are the following ways to remove first and last characters from a String:

1. Using String slice() Method

The slice() method returns a part of a string by specifying the start and end indices. To remove the last character, we slice the string from the start (index 0) to the second-to-last character.

2. Using String substring() Method

The substring() method extracts the part of a string between two specified indices. To remove the last character, provide 0 as the starting index and the second-to-last index as the ending index.

3. Using String substr() Method

The substr() method returns a portion of the string starting from a specified position for a given length. Use it to remove the last character by specifying the starting index and reducing the length by 1.

4. Using Array Methods

Convert the string into an array, remove the last element using the pop() method, and join the array back into a string.
