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

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');

Answer 3

Regular expressions look handy in this case:

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

This will find the last comma in a string and replace it with "and" and anything that came after it.

Answer 4

var strings = ambassadorName.split(",");
strings[0] + ", " + strings[1] + "and " + strings[2];

Use a loop to iterate over the strings array and use size() - 1 to decide when to put the "and"
