Arrays.

i recently have been taking a deep dive into arrays to improve my comprehension of the topic, well, i'm not an expert yet, but i can share a few things that i feel are vital for all developers to have a deep understanding of the topic.

This array tutorial is going to be a series of blogs posts that covers both simple stuff like how to create an array, all the way to complex stuff topics such as the fisher yates method.

Enough talking, let's get our hands dirty and write some javascript.

What is an Array ?

an array is a collection of items stored at contiguous memory locations. The idea is to store multiple items of the same type together.

let me run you through an introductory lesson on how to manipulate arrays.

How to create an array in javascript.

// method 1 of creating arrays
const cars = ['saab', 'Volvo', 'BMW'];

How to access an array.

// Accessing Array Elements
const cars = ['saab', 'Volvo', 'BMW'];
let car = cars[0];
console.log(car);

Changing Elements in an array.

// changing an element in an array
cars[0] = 'opel';
console.log(cars);

Checking the length of an array

const fruits = ['banana', 'apples', 'guavas'];
console.log(fruits.length);

Accessing the first Element in an array

// Accessing the first element in an array
console.log(fruits[0]);

Accesing the last element of an array.

// Accessing the last element of an array.
console.log(fruits[fruits.length - 1]);

Conclusion

That pretty much covers the fundamentals on how to manipulate arrays.

in the next blog post i will show some useful array methods.

Happy Hacking nerds !!!
