Know what variables are and datatypes and create a few then print them (console.log()). See whats going on.
Then use the mathematical operators and do the same. Make some math operations with different datatypes and see what happens.
next would be loops and decisions (if, elseif, switch)
then use object notation
var hey = {
y: 0,
name: "string",
price: 4.20
}
and Object.create();
then use functions
then objects of functions AKA class (keyword new)
Theres new stuff like class and let you should check out
