NOTE

NOTE is an esolang created by User:ResU in 2021. It uses one-based indexing.

Arrays

Arrays are created like this: example = Hello, world! In this case, example/1\ is Hello, and example/2\ is world!. example/x\ also works for strings. example/x\/y\ is the yth letter of the xth word.

Error

When an error occurs, "Never Gonna Give You Up" plays. After the video stops rickrolling you, you can use the ".open/example.com\" command which sends you to example.com.

Commands

Command	Description
.replace/example, 1, "x"\	Replaces the second item in example with "x". It can also append an item to the end of example.
.if	Is an if statement.
.length/example\	Is the amount of items in example
.while	Is a while loop.
.print/"x"\	Prints "x".
!	Is a NOT gate.
|x	All programs of this type where x is replaced by anything (except /n) are nops.
.debug/\	Debugs the code in the console. Argument optional. The argument gets printed.
.import/example.nt\	Imports all functions defined in the program example.nt.
.define/x,y,z\ }	Defines a function with the name x, and arguments y and z.
.do/x=x+1\	Adds 1 to x. .do/x\ does x.
.str/x\	x is converted to a string.
