Homework Hacks

Hack #1

# Create a list of numbers
numbers = [10, 20, 30, 40, 50]

# Print the second element in the list
print(numbers[1])  # Indexing starts from 0, so 1 refers to the second element

Hack #2

%%js

// Create an array of numbers
let numbers = [10, 20, 30, 40, 50];

// Log the second element in the array
console.log(numbers[1]);  // Indexing starts from 0, so 1 refers to the second element

Hack #3
