basic: assign
simple: print, condition, for, plot 
compound: function, class

(basic)

assign:

numbers: var x = 1
strings: var y = string this is a string
words: var z = berry
var_refs: var a = @ b
booleans: var c = bool true/false/1/0
arrays: var num_arr = [1,2,3,4,5]

(simple)

print:

words: print word
var_refs: print @ x/@ num_arr/@ num_arr[1]
strings: print string now printing a string
and evaluate: print eval (1+2+3)

condition:

equality: if word = word print yes
greater: if @ x > 1 print string x is greater than 1
less: if 2 < @ y print num_arr[1] 

for:

words: for 1 times : print greenBerry
strings: for 2 times : print string greenBerry is great
var_refs: for 3 times : print @ x/@ num_arr/@ num_arr[1]

plot:

linear graph: plot 1,2,3,4,5 x-time 4,8,15,16,23,42 y-numbers

(compound)

function:

declaration: func name : print string functions are easy
with parameters: func p x : print @ x
call: call name

method call: make Dinosaur roar
check attribute: see strength of Dinosaur
