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!
