Challenge 16

[The reindeer have made it clear: they will expose 💋 Crystal Claus for her affair with Jamie Glittergum to 🎅 Santa if 💋 Crystal can't convince 🎅 Santa how to give the reindeer a raise.]

[🎅 Santa] Across the whole internet, all I see is adult children! WHAT'S IT GOING TO TAKE TO GET PIPELINE OPERATORS INTO THIS FORSAKEN LANGUAGE!?!

[💋 Crystal] Dear, stop reading the Node.JS release notes. The TC-39 is gonna keep pipeline operators at stage 2 for the next 100 years at this point. Come. Have some some dinner. I've made curry.

[The two eat dinner together, but 🎅 Santa starts to feel a little strange...]

[💋 Crystal] Are you feeling alright, Dear?

[🎅 Santa] No, in fact... I'm not. I'm feeling a bit fuzzy.

[💋 Crystal] That's great to hear.

[🎅 Santa, eyelids getting heavy] What?

[💋 Crystal] I had a friend of mine, Jamie Glitterglum, brew a magic memory implanting glitter potion. This will all be over soon, Dear.

[🎅 Santa, fading] How could you... do... that...

[💋 Crystal] You'll fall asleep, and then I'm going to have a little talk with your subconscious mind. Christopher Nolan can't hold a candle to what Jamie can do.

Well that took a dark turn. You're an accessory to the crime, now. Congrats. Now you have no choice but to help 💋 Crystal with the coverup.

The originalCurry had to have some special ingredients added to it, but 💋 Crystal couldn't be sure if 🎅 Santa would see her cooking. So, to avoid raising suspicion, she had to find a way to be able to add the ingredients at different times.

Hint

This is a process called "currying". Also known as "partial application". To accomplish this challenge, it's first good to get familiar with how to separate function arguments in TypeScript. Check out the Parameters builtin utility type to see how you might get started.

Expected Behavior

const originalCurry = (
	ingredient1: number,
	ingredient2: string,
	ingredient3: boolean,
	ingredient4: Date
) => true

const spikedCurry = DynamicParamsCurrying(originalCurry)

// Direct call
spikedCurry(0, 'Ziltoid', true, new Date())

// Partially applied
spikedCurry(1)('The', false, new Date())

// Another partial
spikedCurry(0, 'Omniscient', true)(new Date())

// You can keep calling until the cows come home: it'll wait for the last argument
spikedCurry()()()()(0, 'Captain', true)()()()(new Date())

// currying is ok
spikedCurry(0, 'Spectacular', true)

// @ts-expect-error arguments provided in the wrong order
spikedCurry('Nebulo9', 0, true)(new Date())
