String.prototype.split() — split with limit

📖 Usage Example

'a,b,c'.split(',')    // → ['a', 'b', 'c']
'hello'.split('')     // → ['h', 'e', 'l', 'l', 'o']
'hi'.split()          // → ['hi']

Use split() to divide a string into an array of substrings at each occurrence of the separator.

String.prototype.split() — Limit

The optional second argument limits the number of substrings returned.

Challenge: Implement splitFirst(str, sep) that returns at most 2 parts.

splitFirst('a,b,c,d', ',') // → ['a', 'b']
