if (isThisAwesome) {
alert('yes'); // it's not
}
// Awesome
isThisAwesome && alert('yes');
// Also cool for guarding your code

It seems that Chrome finally found a way to let us convert from svg to canvas to png without the tainted canvas security feature/bug.

Solve the "Coin Change" coding challenge https://www.hackerrank.com/contests/programming-interview-questions/challenges/coin-change
#!/usr/bin/env node
// Solve the "Coin Change" problem using a bottom-up dynamic programming
// approach. The time complexity is O(n * coins.length) since we have a nested
// loop. The storage complexity is the same, as we store a matrix.
//
// * `coins` is an array of the coin values, eg. [ 1, 2, 3 ]. We assume it
// to be non-empty.
// * `n` is the amount, eg. 4 cents.
