When JavaScript Almost Made Me Quit — Understanding Promises Through the “Cooking Analogy”

Starting software engineering with zero coding background can feel like stepping into a world where everyone speaks a language you’ve never heard before. As a beginner, especially when you’re working with a deadline like I am, it’s so easy to feel overwhelmed, question your decision, or even regret choosing this path.

Honestly? I was doing just fine… until I encountered Promises in JavaScript.

From the start of the module, my course provider warned us:

“This is one of the most challenging topics in JavaScript for beginners.”

Did I take the warning seriously? No. I just jumped right in, confidently.

And then? Boom. I got stuck. I struggled. I spent days on it. I felt stupid. I even paused my lessons at some point because my brain refused to cooperate.

But one thing that finally helped me absorb the concept was writing about it in my own words, using examples that made sense to me. So I’m sharing it with you too — because if you’re a beginner, I know exactly how defeating JavaScript can feel sometimes.

Please, don’t give up. You’re not alone, and struggling doesn’t mean you can’t do this. It just means you're learning.

Let’s Break It Down: JavaScript, Asynchrony, and Promises

Before understanding promises, we need to fix a common misunderstanding.

⭐ JavaScript is single-threaded — it can run only one thing at a time.

So how does JavaScript deal with slow operations like:

• Fetching data

• Waiting for a timer

• Reading a file

• Calling an API

without freezing?

That’s where asynchronous behaviour comes in—but here’s the truth:

⭐ JavaScript itself is NOT asynchronous.

It delegates long tasks to the browser or Node.js environment to handle in the background.

JavaScript keeps working… The browser handles the slow task… And when it’s done, it sends the result back to JavaScript.

So no, JavaScript doesn’t literally run multiple things at the same time—but it creates the illusion of doing so because of this delegation system.

And that brings us to Promises.

The Food Analogy That Finally Made Promises Make Sense

Imagine you're cooking.

You put rice on the fire. Does that mean you must stand there and stare at it for 20 minutes?

No.

You:

• Put the rice on the fire

• Leave it to cook in the background

• Go and cut vegetables, wash chicken, or prepare stew

• When the rice is done, it notifies you by steaming, smelling ready, or the timer ringing

This is exactly how promises work:

• You start a task that takes time

• JavaScript doesn’t wait around

• It continues doing other things

• When the task is done, it notifies you through .then() or .catch()

The rice cooking = the Promise running; You doing other things = JavaScript continuing; The timer going off = Promise resolved.

Simple.

What Is a Promise, in the Simplest Words?

A promise is a JavaScript object that represents a value you will get later.

It says:

“I’m doing something in the background. I will either resolve with a result or reject with an error.”

The Simplest Promise Example

• resolve() = everything went right

• reject() = something failed

• .then() is what you do when the rice is ready

• .catch() is what you do if the rice burns

A More Realistic Example (Like Fetching Data)

In real projects, this waiting is usually for:

• API calls

• Database queries

• File operations

JavaScript won’t pause everything while waiting—it lets the environment handle the slow task and continues working.

Dear Beginner… Don’t Quit Because of One Hard Topic

When you hit a difficult concept like promises, async/await, closures, or the event loop, remember:

💛 Your confusion is not a sign of failure.

💛 Every engineer has struggled with these.

💛 You only need the explanation that works for your brain, not theirs.

And once you finally understand it, the feeling is incredible.

This journey isn’t supposed to be easy — but it is absolutely worth it.

If JavaScript is making you want to quit today, just breathe. You’re learning a new language, a new way of thinking, a new world. You’re allowed to struggle.

But you’re not allowed to give up.
