A Journey Into Building a Fast Text Editor With JS & Canvas!

Text editors have a way of looking simple but managing and painting text is no small task, this talk will give us a look into what bits(literaly) and pieces go into making a fast text editor with Javascript & Canvas. We'll look into what format the text you type is stored in, how it's mutated and highlighted, and how all of this is translated onto a canvas in less than the time it takes you to blink. As a by product we'll get to see how a regular expression engine is implementated and why games use draw distance to save precious hardware resources.

var length = 1024*100; // enough to store 100kb of instrutions at any time
var action = new Uint8Array(length);
var memory = new Array(length);

// action carry instructions with pointers to memory for where to find the nodes to act on
// memory carries nodes that exist in memory

// for example
