Array to Comma separated string and for last tag use the 'and' instead of comma in jquery

javascript, jquery

Solution

You can use `.slice()`:

> var a = [1, 2, 3, 4, 5];
> [a.slice(0, -1).join(', '), a.slice(-1)[0]].join(a.length < 2 ? '' : ' and ');
'1, 2, 3, 4 and 5'

- `a.slice(0, -1).join(', ')`: takes all but the last element and joins them together with a comma.

- `a.slice(-1)[0]`: it's the last element.

- `.join(a.length < 2 ? '' : ' and ')`: joins that string and the last element with `and` if there are at least two elements.

Problem

I have checked many questions and answers regarding join array with comma separated string, But my problem is that, I am making the string readable for human i.e I have tags array that's if their is two tags, then it would be `tag1 and tag2` and if their is 100 tags then it would be `tag1, tag2, ,,,tag99 and tag100` for last one use the `and` and before using the comma as a separator. Any way to handle in JQuery?
