I want to replace last comma with "and " in a string using javascript [duplicate]

Question

I want to replace last comma in a string with and... for eg

var ambassadorName = test, test, test

the output must be

var ambassadorName= test, test and test. 

Please help me with the code

Answer 1

Using regex you can do:

ambassadorName.replace(/,(?=[^,]*$)/, ' and')

I hope it works.

Answer 2

You can do it like this:

var ambassadorName = "test, test, test";
ambassadorName = ambassadorName.replace(/,([^,]*)$/, 'and $1');
