TypeScript: .map() only works for Arrays, not for tuples.
Solution:
function mapPair<S, T>(pair: readonly [S, S], mapFunc: (value: S, index: number) => T): [T, T] {
return [
mapFunc(pair[0], 0),
mapFunc(pair[1], 1),
];
}

JSON hijacking allows an attacker to extract data from a JSON API you serve. The solution? Start the JSON response with a for loop (!). #security dev.to/antogarand/why-facebo…

Love how the side-effects of global window listeners can be totally encapsulated with hooks.
For example, this is used like: const {x, y} = useCoordinates();
The consumer doesn't have to care or worry about the details of window event listening. 😍

Jest 23.5 now supports .each statements: lay out multiple scenarios in a tabular format! Much more concise and readable than copy/pasting tests for each scenario.
Example with 4 scenarios:
Before: 68 lines, copy/pasted 👎
After: 12 lines 👍
