JS Practice — Built-in Objects

String.prototype.repeat() — count of 1

📖 Usage Example

'ab'.repeat(3)    // → 'ababab'
'-'.repeat(5)     // → '-----'
'x'.repeat(0)    // → ''

Use repeat() to create a new string with the original repeated a specified number of times.

String.prototype.repeat() — Count 1

str.repeat(1) returns a new string equal to the original.

Challenge: Implement repeatOnce(str) that returns the string repeated once.

repeatOnce('hello') // → 'hello'
