Can you push to a const array in JavaScript?

Do you know what will be the output of this code?

JavaScript 
const arr = [1];
arr.push(2);
console.log(arr);
Show answer and explanation

The answer is [1, 2].

const only stops arr from pointing to a different value. The array itself can still be changed. Use Object.freeze to make it read-only.
