JavaScript Arrays

Arrays in JavaScript are used to store multiple values in a single variable. They can hold elements of any data type and are zero-indexed.

Common Operations:

• Create an Array:
  let fruits = ["Apple", "Banana", "Cherry"];
• Access Elements:
  console.log(fruits[0]); // Apple
• Add/Remove Elements:
  • fruits.push("Mango"); // Add at end
  • fruits.pop(); // Remove from end
  • fruits.unshift("Grapes"); // Add at start
  • fruits.shift(); // Remove from start
• Iterate:
  fruits.forEach(fruit => console.log(fruit));
• Length:
  console.log(fruits.length); // Number of elements

Advanced:

• Sort:
  fruits.sort();
• Filter/Map/Reduce:
  let result = fruits.filter(fruit => fruit.startsWith("A"));

Arrays are versatile and widely used in JavaScript for data manipulation and storage.
