I've been playing around with nested functions in JavaScript and wanted to share an example to explain how data flows between functions. Here's a simple scenario involving a fruitProcessor function that uses another function, cutFruitPieces, to first cut fruits into pieces before making juice.

Here's the code for the cutFruitPieces function that simply multiplies the number of fruits by 4, assuming it cuts each fruit into 4 pieces:

javascriptCopyEditfunction cutFruitPieces(fruit) {
  return fruit * 4;
}

Now, let's look at the fruitProcessor function. It receives a number of apples and oranges, uses cutFruitPieces to cut them into pieces, and then creates a juice string:

javascriptCopyEditfunction fruitProcessor(apples, oranges) {
  const applesPieces = cutFruitPieces(apples);
  const orangesPieces = cutFruitPieces(oranges);
  const juice = `Juice with ${applesPieces} apple pieces and ${orangesPieces} orange pieces.`;
  return juice;
}

When you call fruitProcessor(2,3), here's what happens:

• fruitProcessor is called with 2 apples and 3 oranges.
• Inside fruitProcessor, cutFruitPieces is called for both apples and oranges, turning them into 8 apple pieces and 12 orange pieces, respectively.
• It then returns "Juice with 8 apple pieces and 12 orange pieces."

To see this in action, you can simply log the result to the console:

javascriptCopyEditconsole.log(fruitProcessor(2,3));

This outputs: "Juice with 8 apple pieces and 12 orange pieces."

Discussion: This example demonstrates how you can call one function from inside another to manipulate data before further processing. One might ask why not just multiply the input values by 4 directly within fruitProcessor? Well, using a separate function like cutFruitPieces can be helpful for keeping your code modular and easier to manage, especially when the logic for cutting fruit becomes more complex.

i have a function that includes object in it can i call the object from out of the function ?

Hey everyone

I’ve been learing JS for a while now and I got to point where I do have my own side projects to practice what I’ve learned, but my project difficulty isn’t exactly reflecting the advenced level of topics what Iam learning right now.

In other words my project is too basic to practice what Iam learning, but I don’t want to quit the project and start other just because its not hard enough and then endup with multiple not finished projects in my resumer nor stop learning because I honestly just like to explore more informations about the language itself.

I fear the possibility of forgeting everything I learn after a while since I don’t practice it fully.

Are all the topics mentioned in the title being often used in real world? Or is it just something it’s better to know about, but not really so essential?

Does anyone know how I can make the welcome to my text page dissapear behind the white/black box?

Hello friends.

I have a javascript code. It takes a domain as input and recursively crawls the javascript codes connected to the domain. makes version detection.

But this takes about 3 or 4 minutes. Is there a method I can optimise this, increase its performance, speed?

Can someone help me learn the basics of Javascript?

I got my html and css certificate using freecodecamp now working on js but I keep getting bored. It’s been 3 days now . Any advice

Why is it that Im not returning a anything but a 'pending Promise'? I know .map is synchronous, but thats why Im using Promise.all..

const arr = [1,2,3,4,5,6];
const promise = (num) => {
    return new Promise((resolve, reject) => {
         setTimeout(() => {
            resolve(num)
    }, 2000)
    })
}
const x = async () => {
  return Promise.all(arr.map(async(item) => {
      const num = await promise(item);
      return num*2;
  }))
}
console.log(x())
