The substring Method

Another way to extract

The substring() method also extracts parts:

let text = "JavaScript"
console.log(text.substring(0, 4))  // "Java"
console.log(text.substring(4, 0))  // "Java" (swaps if needed)

Unlike slice(), substring() treats negative numbers as $0$ and swaps arguments if start > end. Prefer slice() for its predictable behavior with negative indices.
