Continuation of function - Arrow function.

An arrow function is a concise way to define small, single-purpose functions in JavaScript.

Arrow Function Structure;

Const AddNum= ( ) => {
}

Now, Let's look into Arrays and Array Methods.

An Array is a list-like structure that stores multiple values in a single variable. Each item in the array has an index, starting from 0.

Also, an array is a data structure that stores a collection of elements, each identified by an index or key.

Array Methods:

1. Push: Adding elements to the end of the array (e.g.array.push(element)).

2. Pop: Removing the last element from the array (e.g. array.pop()).

3. Shift: Removing the first element from the array (e.g., array.shift()).

4. map(): Creates a new array with the results of applying a function to each element

5. filter()*: Creates a new array with elements that pass a test.

6. reduce()*: Applies a function to each element, accumulating a value.

7. forEach(): Iterates over the array, executing a function for each element.

Benefits of Arrays

1. Efficient data storage: Arrays provide a compact way to store collections of data.

2. Fast access: Arrays allow for fast access to elements using their index.

3. Flexible: Arrays can be used in a variety of contexts, from simple data storage to complex data processing.
