Question

[3, 4, 5]
['4', '1', 'abc123']


function combine_ids(ids){
    return ids.join(',');
};

No matter what type of list, I want my function to return a string with single quotes around the elements.

The function should return:

'3','4','5'

and

'4','1','abc123'

I want my resulting string to have single quotes in them!

Answer 1

Simple logic!

function combine_ids(ids) {
  return (ids.length ? "'" + ids.join("','") + "'" : "");
}
console.log(combine_ids([]));
console.log(combine_ids([3]));
console.log(combine_ids([3, 4, 'a']));

Example output:

(an empty string)
'3'
'3','4','a'
