The new string should be later stored in the variable "strnew".

We are using the method substrwhich allows us to return parts of a string. Substr takes two parameters: The first parameter is the location of the start and the second parameter is the length of our substring number of characters. In order to delete the last character, we proceed as follows: We want to extract a substring starting from the first character of the original string.

So our first parameter is 0, because in JavaScript, the first character is the 0th character. From this character on, we want to keep as many characters as the string is long up to one character at the end. So, we can get the length of the old string with "strold. To illustrate this, here is just another example in which we want to delete the first and the last character from a string in JavaScript:.

If we also do not want to keep the first character of the string, we have to start at 1 rather than at 0. Thus, our first parameter is 1, so that we can cut the first letter of the string.

From this character on, we want to keep as many characters as the string length minus 2. If we would subtract 1 again as in the last example, we would keep our last character here, because this time, we are starting one character from the beginning.
