// Assuming the user wants to extract the leftmost 'n' characters from a string or array

// For string:
const str = "Hello World";
const n = 5;
const leftSubstring = str.substring(0, n);
console.log(leftSubstring); // Output: "Hello"

// For array:
const arr = [1, 2, 3, 4, 5];
const leftElements = arr.slice(0, n);
console.log(leftElements); // Output: [1, 2, 3, 4, 5]
