JS Practice — Built-in Objects

String.prototype.split() — split by character

📖 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()

str.split(separator) splits the string into an array of substrings at each separator.

Challenge: Implement splitByComma(str) that splits a comma-separated string.

splitByComma('a,b,c') // → ['a', 'b', 'c']
