PRIMITIVE DATA TYPES
Number: This can be integers, decimal or floating point numbers.There are also special numbers namely; Infinity and NaN. Infinity is gotten by division with zero and NaN is as a result of incorrect mathematical operation.
Strings: They represent textual data. Strings can be a single character or combination of different characters. Single quotes, double quotes begin and end strings e.g 'sugarcrush' or "sugarcrush".
Boolean: Boolean values can either be True or False. A truthy value simply means yes and a falsy value means no.
Undefined: When a value of undefined is assigned to a variable, this denotes that a value has not been assigned to it. We can also define an undefined value by just declaring a variable without assigning it to any value or explicitly giving it a value of undefined.
