What are some of JS' primitive data types?

#javascript #codenewbie #motivation

PRIMITIVE to me means BASIC! Like a caveman...and you literally cant build anything without basic data. primitive data type is data that is not an object and has no methods.

Some of the Primitive data types:

NUMBERS
STRING
BOOLEAN
UNDEFINED
NULL

Examples of Javascript numbers

100     //Integers
50
1.1     //Floats
100.69

Examples of Javascript strings

"Hi!"     //you can define a 'string' by double quotes.
'Hi!'     //you can also define a 'string' by single quotes.
"30"     // this is also a string

Examples of Javascript booleans

true  // Booleans only state is 'true' or 'false

false // It is either on or off, yes or no!!

Examples of Javascript null & undefined

// null means that there is no value assigned..empty
// and is intentionally set
// undefined means that the container exists
// but hasnt been given a value

console.log(null === undefined);  //false
console.log(null == undefined);  // true

Another day in the life using primitive data types in a loop

//while some number is less than 10, console.log('string type')

let i = 1;

// while something is true..run this scoped code
while (i < 10) {
  console.log('string type', i)

i += 1 // i = i + 1

}
