I was asked this question in an interview and was totally unprepared! I knew generally what it was as I reviewed some material the week prior but I did not give enough of a concise answer to prove I knew what I was talking about. So here I’ll be answering, “What is object oriented programming (OOP)?”

Object oriented programming is based on the idea of using objects to represent data and methods. We use classes as a blueprint to create an object. Classes do not contain any data but it will define what properties and operations can be performed.

String reversals are one of the most common questions on tech interviews. There are many different ways to do this and one way I’d like to do this is by…

The next part of my Data Structures series is binary search trees.

A Binary Tree is a data structure where each node can have 0, 1 or 2 nodes. Each child can only have 1 parent.

The benefits of using a binary search tree are the look up times are better than O(n), the tree is ordered and the size is flexible. Trees are useful because you can find data going into a subset of the data instead of searching through every element in the tree. A balanced binary search tree look up times are O(log(n)) for access, search, insert…

To continue the data structure series I have going on, I’ll be talking about objects in this post.

My previous post on arrays can be found here.

Objects are another data structure that has a key and value pair. Object data cam be accessed through properties. Using objects as a data structure is faster than arrays when looking up data.

let cat = {
    name: 'Bella',
    color: 'orange',
    personality: 'fiesty',
    friends: 'Cookie',
    enemies: ['Acrobat', 'Daemon', 'Barack']
}//To access the friend data inside the cat object, you can use dot notation:cat.friends // 'Cookie'To access enemies data inside an…

While taking a udemy course for data structures and algorithms I have learned that there are many other types of data structures than the ones I’ve been using which are arrays and objects. There are arrays, objects/hashes, linked lists, stacks and queues, trees, and graphs. I’ll be doing a simple break down of each data structure starting with arrays.

Arrays are one of the simplest forms of data structures. Arrays can contain strings, numbers and booleans as well as a combination of different data types within the same array.

let array = [1, 2, 3, 4, 5]
let array2 = ['apples…

I can’t tell you how many times I forget the difference between “.splice” and “.slice” when I’m doing an algorithm and trying to decide which one to use. So here are some examples to help me and anybody else who struggles with remembering to understand the differences.

.slice()

• extracts a part of the array and returns the selected elements in a new array.
• takes in two arguments. First argument is the start and second argument is the end but does not include the given end argument.

let flowers = ['forget me nots', 'dahlias', 'roses', 'daisies', 'tulips']
flowers.slice(0, 2)returns ['forget me…

“Regular expressions are patterns used to match character combinations in strings. In JavaScript, regular expressions are also objects.” — MDN web docs

There’s a saying that goes, ‘face what you fear.’ Every time I looked at regex I cringed because I had no idea what all those forward slashes, back slashes and letters and numbers meant but I decided to face my fear and dive into understanding it.

Flags:

/i : ignores case of letters

Example:const myString = 'Face what you FEAR!'let ignoreCase = /fear/ilet result = myString.match(ignoreCase)returns true

/g : finds more than the first…
