JAVA SCRIPT BASICS

Hey everyone!

Today i'll just be posting a few things about java script that i learnt last week.

Starting off with the variable name syntax;

Naming a variable on java script is quite different from python.

Java script involves the use of the key words: let, **

** or var.

These keywords however have slight differences apart from their names of course!

The let keyword allows you to change values while the const does not. **var **is similar to let but is an older method and is not in use anymore.

Syntax is;

let name of variable = value;

const name of variable = value;

var name of variable = value;

For example:

let nameOfCat = "Fred";

nameOfCat

'Fred'

The value of the variable can be changed:

nameOfCat = "Sam";

nameOfCat

'Sam'

For const however, the value of the variable cannot be changed!

const nameOfCat = "Fred";

nameOfCat

Fred

nameOfCat = "Sam"; XXXX (This will show a type error because the constant variable cannot be reassigned)

Note: When naming variables on java script, camel case is most preferred e.g nameOfCar rather than snake case (name_of_car) which is preferred in python.

That's all for today, see you in my next blog post!
