// Define a function called `remove_from_left` that removes elements from the left side of an array.
function remove_from_left(arr, n = 1){
  return arr.slice(n); // Slice the array from index n to the end
}

// Example usage
console.log(remove_from_left([1, 2, 3])); // [2, 3]
console.log(remove_from_left([1, 2, 3], 1)); // [2, 3]
console.log(remove_from_left([1, 2, 3], 2)); // [3]
console.log(remove_from_left([1, 2, 3], 4)); // []
