Slice Array Method Javascript

• The slice method is used to create a shallow copy of a portion of an array, without modifying the original array.
• Doesn't mutate the original array.

Syntax:

array.slice(start, end);

• start (optional): Index to begin extraction.
  • Defaults to 0 if not provided.
• end (optional): Index to stop extraction (excluded from result).
  • Defaults to the array's length if not provided.

Example

const numbers = [1, 2, 3, 4, 5];
const result = numbers.slice(1, 4);
console.log(result); // Output: [2, 3, 4]
console.log(numbers); // Original arrray remains unchanged
