Consider the following superheroMaker function. What gets logged ?

const superheroMaker = a => { return a instanceof Function ? a() : a; }; console.log(superheroMaker(() => 'Batman')); console.log(superheroMaker('Superman'));
When passing () => 'Batman' to superheroMaker, a is an instance of Function. Therefore, the function gets called, returning the string Batman. When passing 'Superman' to superheroMaker, a is not an instance of Function and therefore the string 'Superman' is just returned. Therefore, the output is both Batman and Superman.

JavaScript Tip 💡

Avoid default exports.
You will get a way better developer experience, especially if you're using TypeScript.

If you're using CommonJS, you can spare yourself the annoying "
.default" when you require.

It's a great coding habit ✌️

What gets logged in the following code?

let i = 0; const arr = new Array(5); arr.forEach(() => i++); console.log(i);
Array methods like map, filter, reduce, forEach, etc take a callback as the first parameter, which is executed for every element in the array. The Array constructor, when given an integer between 0 and (232 - 1), will return a sparse array, which has a length property equal to the given integer. The returned array is "sparse" because its slots are empty; it does not have any own-properties, other than .length. (In contrast, the array [undefined] does have an own-property of 0, even though the value at that property is undefined.)

💛 JavaScript tip 💛

One common issue when dealing with JSON de-/serialization is with date strings. You serialize a date but then deserialize a string. You simply lose type information.

Gladly, there is a fix for that, a reviver function, and here is how you use it!
