Stepping into the world of coding, I thought would be opening a different world of possibilities. It did. But in my head I felt like I was thrown into the ocean not knowing how to swim. A bit dramatic, aren’t I? For reference my background was health care. I was not technically a first responder, but had a very important role anyhow. Prior to starting the boot camp that I am currently enrolled in, we were instructed to finish a pre-work course which consisted of about 40-60 hours of lecture and lab, and I finished it a week or so before the first day of class.
I thought that had prepared me from the ocean that I was about to embark on. I was excited, nervous, giddy that I would be learning more information. I had my laptop ready, cup of tea next to me, and an emergency coffee on standby just in case, eager to face the day. I guess I did forget how a first day in school feels. It has been 10 years plus since I have been in school. Gosh, do I feel old writing that. I felt happy, eager, lost, confused, and anxious all at the same time.
It has been exactly 5 days since I started my boot camp school. I still feel all the emotions everyday. Up and down, right and left, making circles, what a rollercoaster the first week feels. What got me through the lows, was making myself a cheat sheet. I would like to share some parts of the cheat sheet that I made as I went through the course and labs in this first week. Comment if you need any clarifications or anything to improve my cheat sheet!
I think I've learnt a huge amount in a very short amount of time, hopefully this blog helps somebody going through the same situation, you're not alone, you've got this!
JavaScript Basics:
Variables
- they store values, ex: const variableName = “This is a string.”
| Variable | Re-assignable? | Scope: | Use it? |
|---|---|---|---|
| let | yes | block-scoped | yes |
| const | no | block-scoped | yes |
| var | yes | Global or function | Avoid it! |
Data types
- Number
- String
- Boolean
- Object
- Undefined
- Null
- BigInt
- Symbol
Functions
1. Function Declarations
function addition(number1, number2) {
return number1 \+ number2;
}
addition(5, 10);
Expected return: 15
2. Function Expressions
const sum \= function addition(number1, number2) {
return number1 \+ number2;
}
console.log(sum(5, 10));
Expected return: 15
3. Arrow functions
cons sum \= (number1, number2) \=\> number1 \+ number2;
sum(5, 10);
Expected return: 15

DOM / HMTL
The DOM, Document Object Model, is a way of representing a document as a series of nodes, and defines the interface for interacting with those nodes. HTML, HyperText Markup Language, is used to create a representation of the DOM that then can be modified by javascript, using the APIs defined by the DOM.
