How to remove last few characters of String using JavaScript Slice ?
Every time trim the last 6 characters from the phone number.
For example, +919895590123
and make it +919895
. Now you can use slice
straight away if you know where to end.
'+919895590754'.slice(0,7)
// ## `+919895`
But it doesn’t work is it’s different length phone number like +1219895590345
.
So the solution would be to use negative index for end parameter.
'+1219895590345'.slice(0,-6)
// ## '+1219895'
