Spread Operator is a Joke!

Hey there, folks! Today, let's take a hilarious trip down memory lane and talk about JavaScript's spread operator. Some folks swear by it, but let's not forget the good old days when life was simpler, and coding was a real adventure. Buckle up, because we're about to embark on a journey filled with laughter and nostalgia!

The Confusion Before Spread

Think back to a time when coding felt like solving a Rubik's Cube blindfolded. The spread operator? Non-existent! Concatenating arrays and cloning objects were like solving riddles without clues. But hey, who needs shortcuts when you can enjoy the scenic route?

Concatenating Arrays: A Herculean Task

Let's reminisce about the days when joining arrays was a true test of patience and wit. No spread operator to rescue us, just good old loops and arrays. It went something like this:

const arr1 = [1, 2, 3];
const arr2 = [4, 5, 6];
let concatenatedArray = [];
for (let i = 0; i < arr1.length; i++) {
    concatenatedArray.push(arr1[i]);
}
for (let i = 0; i < arr2.length; i++) {
    concatenatedArray.push(arr2[i]);
}
console.log(concatenatedArray); // [1, 2, 3, 4, 5, 6]

Ah, the joy of manual labor! Who needs shortcuts when you can flex those coding muscles?

Cloning Objects: A Journey Through Object Land

And let's not forget the adventure of cloning objects – a maze of keys and values without the spread operator to guide us. Here's a glimpse into the madness:

const originalObject = { name: 'John', age: 30 };
let clonedObject = {};
for (let key in originalObject) {
    clonedObject[key] = originalObject[key];
}
console.log(clonedObject); // { name: 'John', age: 30 }

Oh, the thrill of exploration! Who needs simplicity when you can navigate the labyrinth of objects?

Spread Operator: A Modern-Day Villain

But then came the spread operator, crashing our nostalgic party with its simplicity and efficiency. Concatenating arrays and cloning objects became as easy as pie. Where's the challenge in that?

const arr1 = [1, 2, 3];
const arr2 = [4, 5, 6];
const concatenatedArray = [...arr1, ...arr2];
console.log(concatenatedArray); // [1, 2, 3, 4, 5, 6]

const originalObject = { name: 'John', age: 30 };
const clonedObject = { ...originalObject };
console.log(clonedObject); // { name: 'John', age: 30 }

Ah, the betrayal of progress! Who needs efficiency when you can revel in the chaos of manual coding?

Conclusion: Cheers to the Good Ol' Days!

In conclusion, while the spread operator may have simplified our lives, let's not forget the joy of struggle and the thrill of exploration. Manual coding may have been tough, but it built character and taught us valuable lessons. So here's to JavaScript's missing spread operator – may its absence continue to inspire laughter and nostalgia for generations to come!

Why you should use the spread operator:

function pipe(value, ...functions) {
    functions.forEach(f => (value = f(value));
    return value;
}

// Usage
const finalValue = pipe(initialValue, filter1, filter2, filter3, filter4 /* , filterN */);

Let's reminisce about the days when joining arrays was a true test of patience and wit. No spread operator to rescue us, just good old loops and arrays...

Err, Array.concat? That's been there forever (20+ years)

arr1 = arr1.concat(arr2)

And let's not forget the adventure of cloning objects – a maze of keys and values without the spread operator to guide us.

Really? Object.assign is your friend... (~10 years)

const clonedObject = Object.assign({}, originalObject)
