Week One

Javascript Fundamentals

Over the Course of week 1 we went over Javascript fundamentals

as well as what we will be doing over the next few weeks

Our lessons were as follows:

Monday - Object oriented programming, dot notation and data types
Object oriented programming is a programming methodology based around creating objects with attributes and methods which can be called upon, an example of a method would be "console.log()" and calling upon an attribute would look like "objectName.attributeName". data types are the types of data that can be stored in a variable and the common data types are as follows:
• String - a string of characters
• Number - a numerical value
• Bigint - an exceptionally large number
• Boolean - True or False
• Undefined - the data type wasn't initialized
• Null - the data type was initialized but the value is empty
• Object - a data type that references other data types and functions
Tuesday - Coding fundamentals, computational thinking and variables
Coding fundamentals can be broken down into 3 main categories:
• Sequence - the order in which code is run
• Selection - which code is run based on different conditions
• Iteration - looping sections of code instead of writing it out multiple times
A variable is a storage container for a single piece of data such as a string or a number

Wednesday - Selectors (if and else), arrays and how to access them
The most common way to select which code to run is an if statement which has the following syntax "if (condition) {code to execute if true}". If statements are often followed by an else statement which looks like "else {code to run if condition is false}".
Arrays are a data type that are a sort of list of variables, to initialize an array you can put "arrayName = [example1,example2,example3]"(you can also initialize them with empty square brackets), you can access and alter an array using "arrayName[index]" where index is the location in the list starting from 0

Thursday - Loops/Iteration(for and while) and functions and how to declare them
There are 2 main loops that people use when programming:
• For Loop - a loop that runs a set number of times and is formatted as: "for ((initializer)let i = 0;(condition) i < 10;(iterator) i++) {code to run each iteration}"
• While Loop - a loop that runs until a condition is no longer true and is written as: "while (condition) {code to be run}"
Functions are snippets of code that can be run by being called upon as well as taking parameters to produce a desired outcome, there are multiple ways to declare a function but my preferred way is:
"function functionName(parameter1,parameter2) {code to be run}"
To call upon a function you can use the following syntax:
functionName(parameters)
The number of parameters a function can have are not limited and can be 0 or over a hundred depending on its use

Friday - Javascript challenges

The javascript challenges were basic challenges focused around functions and array manipulation
