Code Typing

Level 1 of 10 · JavaScript

Sum a shopping cart

A cart total with reduce. The brackets close on lines of their own, and the last line uses backticks.

const prices = [4, 12, 7, 9];

const total = prices.reduce(
  (sum, price) => sum + price,
  0,
);

console.log(`Total: ${total}`);

The indentation is typed for you. Enter starts a new line, Backspace rubs a character out, and the clock runs from the first key. A level is solved when the whole snippet is typed at 95% accuracy or better.
