Destructuring & Spread Operator:

1. What is destructuring in JavaScript and how does it work?
2. How can the spread operator be used in JavaScript?
3. What are some practical use cases for using destructuring and the spread operator in JavaScript?
4. How does destructuring and the spread operator differ from traditional assignment and concatenation in JavaScript?
5. Can destructuring and the spread operator be used with non-array and non-object data types in JavaScript?

1- Destructuring is a feature in JavaScript that allows you to extract values from arrays or objects and assign them to variables in a more concise way. Instead of accessing each value using its index or key and assigning it to a variable, destructuring allows you to do this in a single line of code.

2- We can create a shallow copy of objects and arrays using the spread operator because the objects and arrays are non-perimitive values, and use pass-by reference with them.

3- When we want to a copy of an array or obj we need to use the sperade operator cuz there is no other way to create a real copy directly so we can make a shallow copy, and for the restructuring, it is useful for extract values from objs or arrays and assign them into variable

1. Destructuring is a JavaScript expression that makes it possible to unpack values from arrays or properties from objects into distinct variables. For example, if you have an array x with values [1, 2, 3, 4, 5], you can use destructuring to assign the first two values of the array to variables y and z like this: const [y, z] = x;. After this assignment, y will be equal to 1 and z will be equal to 2.
   Similarly, you can destructure objects. For example, if you have an object obj with properties {a: 1, b: 2}, you can use destructuring to assign the values of properties a and b to variables a and b like this: const {a, b} = obj;. After this assignment, a will be equal to 1 and b
   will be equal to 2.

const numbers = [1, 2, 3];
const expandedNumbers = [...numbers, 4, 5];
console.log(expandedNumbers); // Output: [1, 2, 3, 4, 5]

spread opreator uses for shallow copy for an array or object
3. Destructuring use cases: Extracting values from arrays or object, Specifying default values,Swapping variables
spread operator use cases: Merging arrays and objects,Copying arrays and objects, Converting strings to arrays
5. yes, destructuring and spread Operator works with String and functions too

1- Destructuring lets us pull out a specific parts of an array, object or a string. It would be easier to assign values to our variables.
2-spread operator allows us to do shallow copy on arrays, objects and strings. when we use spread operator to copy, and then make a modification to the copied array/objects/strings, it wouldnt affect the original ones.
3-when we want to get some of the attributes from an nested object, we can use destructuring. For spread operator: we can crate new array from the existing one.
4-In traditional assignment, we can create only one variable and assign it at a time. In destructuring, we can easily create and initialize more than one variable at a time. For concatenation: we can use spread operator with strings, objects and arrays.
