Making a small Library in Solidity

So this line really stood out. 😂😂😂

So to work it out, I entered the avatar state to unlock my chakra

You did a good job to make light of the topic. For the getPositiveAndSquare function, you can actually substitute a pipe of filter and map into a single reduce.

const getPositiveAndSquare = arr => {
    return arr.reduce((acc, cur) => {
        if (cur > 0) {
            acc.push(cur * cur);
        }
        return acc;
    }, []);
};

console.log(getPositiveAndSquare([2, 3, 4, 0, 2]));

Though I have no idea of the solidity you talked about. 😓
