JavaScript String slice() Method
The JavaScript string slice() method is used to fetch the part of the string and returns the new string. It required to specify the index number as the start and end parameters to fetch the part of the string. The index starts from 0.
This method allows us to pass a negative number as an index. In such case, the method starts fetching from the end of the string. It doesn’t make any change in the original string.
Syntax
The slice() method is represented by the following syntax:
Parameter
start – It represents the position of the string from where the fetching starts.
end – It is optional. It represents the position up to which the string fetches. In other words, the end parameter is not included.
Return
Part of the string

Output:
tpoint
Example 4
In this example, we will provide negative number as an index. In such case, the method starts fetching from the end of the string.
Output:
point
