My Answer:
In JavaScript, you can create an array and access its elements in a similar way to PHP. Here is an example of how you can emulate PHP array functionality in JavaScript:

javascript

// Create an array

let fruits = ['apple', 'banana', 'orange'];



// Access elements by index

console.log(fruits[0]); // Output: apple



// Add elements to the array

fruits.push('grape');

console.log(fruits); // Output: ['apple', 'banana', 'orange', 'grape']



// Remove elements from the array

fruits.splice(1, 1); // Remove 1 element at index 1

console.log(fruits); // Output: ['apple', 'orange']



// Check if an element exists in the array

if (fruits.includes('apple')) {

  console.log('Apple is in the array');

} else {

  console.log('Apple is not in the array');

}



// Loop through the array

for (let i = 0; i < fruits.length; i++) {

  console.log(fruits[i]);

}

This code snippet demonstrates how you can create, access, modify, and iterate through an array in JavaScript, similar to how you would do it in PHP.
