🔪 Distinguishing slice() vs splice() in JavaScript

Hey folks! Today let’s look into another common JavaScript question: Distinguish between slice() and splice() in JavaScript 🚀

🔷 Slicing Arrays with slice():

slice() is a handy method for extracting a portion of an array. It always creates a new array and does not modify the original array, making it perfect for non-destructive operations. This method takes two arguments: the starting index (inclusive) and the ending index (exclusive). It will return a new array which will contain the elements from the starting index till the element before the ending index.

const fruits = ['apple', 'banana', 'cherry', 'date', 'fig'];
const slicedFruits = fruits.slice(1, 4);
console.log(slicedFruits); // Output: ['banana', 'cherry', 'date']

🔶 Splicing Arrays with splice():

splice() is a powerful method for adding or removing elements from an array. Unlike slice(), splice() modifies the original array so it is destructive. It takes three arguments: the starting index, the number of elements to remove, and optional elements to add. It returns an array of the removed elements.

const colors = ['red', 'green', 'blue', 'yellow', 'orange'];
const removedColors = colors.splice(1, 2, 'purple', 'pink');
console.log(colors); // Output: ['red', 'purple', 'pink', 'yellow', 'orange']
console.log(removedColors); // Output: ['green', 'blue']

🌟 When to use?

• Use slice() when you want to create a new array that's a subset of an existing array without modifying the original.

• Use splice() when you need to remove or add elements within an array, altering the original array.
