LESSON 4: FUNCTIONS IN JAVASCRIPT

There are three important pieces to create a function:
😡 1. Arguments - they are values passed into a function. if i create a function that validates an email, I'd need to accept the email as a function argument.
💻 2. Function Code- the function code is what goes inside of the curly braces. This is where you define what your function does.
📥3. Return Value - This is a part of the function code. It lets you define what value to send back to the function caller.

🤳🤳🏃🏼🏃🏼
Let's see the snippet using a function #[

fahrenheitToCelsius]#


let fahrenheitToCelsius = function (fahrenheit) {
const celsius = (fahrenheit - 32) * (5 / 9)
return celsius
}
let temp70 = fahrenheitToCelsius(70)
console.log(temp70)
let temp32 = fahrenheitToCelsius(32)
console.log(temp32)

LESSON 5: null and undefined in JS

🥃The null value represents the intentional absence of any object value.
🎭The global undefined property represents the primitive value undefined. It is one of JavaScript's primitive types.

[javascript]🌈LESSON 6: Object Basics💦

✳️ It is one the data types in javascript. It is used to store various keyed collections and more complex entities.
const obj = {
property1: value1, // property name may be an identifier
2: value2, // or a number
"property n": value3, // or a string

};

📥You can create a new object by opening and closing curly braces. Below is an object with three properties ; title, author , and page count;

let myBook = {
title: '1984',
author: 'George Orwell',
pageCount: 326
}


❄️ [ RUN ] ❄️

📌Object prototype properties

myBook.valueOf() // show everything inside {}

myBook.hasOwnProperty("p")//return boolean value
And there are many static methods used to increase the functionality of an object

💫OBJECTS WITH FUNCTIONS🌟


☀️Objects can be used as Function arguments

💥getSummary(myBook);

☀️Objects as Function Return Values

🌚
let convertFahrenheit = function (fahrenheit) {
return {
fahrenheit: fahrenheit,
kelvin: (fahrenheit + 459.67) * (5 / 9),
celsius: (fahrenheit - 32) * (5 / 9)
}
}
let temps = convertFahrenheit(74)
console.log(temps)
