0, the second character is
1, third character is
3 and the last character index
To remove the last 2 characters of a string, we can use the built-in slice() method by passing the
0, -2 as an arugments to it. So it returns a new string by removing the last 2 characters from it.
-2 is similar to string.length-2.
Here is an example:
const welcome = 'hello//'; const result = welcome.slice(0, -2); console.log(result);
In the example above, we have passed
0, -2 as an arguments to the
slice() method. so it begins the slicing at index position 0, and extracts before the
string.length-2 character index.
const welcome = 'hello//'; const result =str.substring(0,str.length-2); console.log(result);
substring() method also works similar like
slice method but in
substring() method if first argument index is greater than second argument index then arguments are swapped.
