Q1. What is array and how to modify it
Ans. 
An array is a data structure that stores a collection of elements of the same type in a contiguous memory location.
• To modify an array, you can access individual elements by their index and update them with new values.

• You can also add new elements to the array by assigning values to new indexes.

• Example: let array = ['apple', 'banana', 'cherry']; array[1] = 'orange'; array.push('grape');
