JS Practice — Built-in Objects

String.prototype.split() — split by string

📖 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() — String Separator

The separator can be a multi-character string.

Challenge: Implement splitBySep(str, sep) that splits str by the separator sep.

splitBySep('one::two::three', '::') // → ['one', 'two', 'three']
