In JavaScript, shift and unshift are methods used to add or remove elements from the beginning of an array.

1. Unshift
The unshift method adds one or more elements to the beginning of the array.
This increases the array's length.
It returns the new length of the array.
Example:

javascript
Copy code
let fruits = ["apple", "banana"];
fruits.unshift("orange"); // Adds "orange" to the beginning
console.log(fruits); // Output: ["orange", "apple", "banana"]
2. Shift
The shift method removes the first element from the array.
This decreases the array's length.
It returns the removed element.
Example:

javascript
Copy code
let fruits = ["orange", "apple", "banana"];
let removed = fruits.shift(); // Removes the first element ("orange")
console.log(fruits); // Output: ["apple", "banana"]
console.log(removed); // Output: "orange"
Key Points
Unshift adds elements to the beginning of an array.
Shift removes the first element of an array.
Both shift and unshift modify the original array...#learnhtml5andcss3#codingchallenge #code #webdevelopment #codewithme #codewithharry #frontenddevelopment#codewithharry #education #htmlacademy #htmlcss #css #codehelp #js #upsc #java #codewithharry #frontenddeveloper #javaprogramming #javatutorial #javatutorialsforbeginners #designer #design #engineering #CodingTutorial #CodeWithMe #ProgrammingTips #DeveloperLife#udemy #figma #TechTips #CodingJourney #CodeChallenge #JavaScript#Python #Java #CSharp#Ruby #PHP #TypeScript #WebDevelopment#WebDevelopment
