Can you give me some examples of JavaScript arrays?

Can you give me some examples of JavaScript arrays?

Sure! Here are a few examples of JavaScript arrays:

1. Basic array: let fruits = ['apple', 'banana', 'cherry'];
2. Array of numbers: let numbers = [1, 2, 3, 4, 5];
3. Mixed array: let mixed = [1, 'two', true, null];
4. Nested array: let nested = [[1, 2], [3, 4]]; Do you want to know more about any specific type?

What methods can I use with arrays?

You can use various methods with arrays, such as:

• push(): Adds an element to the end of the array.
• pop(): Removes the last element from the array.
• shift(): Removes the first element from the array.
• unshift(): Adds an element to the beginning of the array.
• map(): Creates a new array with the results of calling a function on every element. Would you like examples of these methods?

Yes, please provide examples for each method.

Here are examples for each method:

• push():

let fruits = ['apple', 'banana'];
fruits.push('cherry'); // fruits is now ['apple', 'banana', 'cherry']

• pop():

let lastFruit = fruits.pop(); // lastFruit is 'cherry', fruits is now ['apple', 'banana']

• shift():

let firstFruit = fruits.shift(); // firstFruit is 'apple', fruits is now ['banana']

• unshift():

fruits.unshift('orange'); // fruits is now ['orange', 'banana']

• map():

let numbers = [1, 2, 3];
let doubled = numbers.map(num => num * 2); // doubled is [2, 4, 6]
