String.prototype.slice() — basic substring

📖 Usage Example

const str = 'Hello, World!'
str.slice(7, 12)    // → 'World'
str.slice(-6, -1)   // → 'World'
str.slice(7)        // → 'World!'

Use slice() to extract a portion of a string by start and end indices, supporting negative indices.

String.prototype.slice()

str.slice(start, end) extracts a substring from index start up to (not including) end.

Challenge: Implement getMiddle(str) that returns characters from index 2 to 5 (exclusive).

getMiddle('abcdefgh') // → 'cde'
