### JavaScript Array Methods

1. .map(🧃): Transforms each element in the array to a new value
Example: Turning a list of teacups into water bottles!

2. .filter(🍵): Creates a new array with all elements that pass the test implemented by the provided function.
Example: Filtering out only the teacups from the array.

3. .find(🍵): Returns the value of the first element in the array that satisfies the provided testing function.
Example: Finding the first teacup in the array.

4. .findIndex(🍵): Returns the index of the first element in the array that satisfies the provided testing function.
Example : Finding the index of the first teacup in the array, which is 3.

* .lastIndexOf(🍵): Returns the index of the last element with a specified value the array that satisfies the provided testing function.
Example : Finding the index of the last teacup in the array, which is 3.

5. .fill(🧃,1): Fills all the elements of an array from a start index to an end index with a static value.
Example: Filling part of the array with water bottles.

6. .some(🍵): Checks if at least one element in the array passes the test implemented by the provided function.
Example: Checking if there’s at least one teacup – returns `True`.

7. .every(🍵): Checks if all elements in the array pass the test implemented by the provided function.
Example: Checking if every item is a teacup – returns `False`.

📌 **Using these functions effectively can significantly improve your code’s readability and performance.**
