= Creating the editor

== Hello world!
=======================JS
// The Monaco Editor can be easily created, given an
// empty container and an options literal.
// Two members of the literal are "value" and "language".
// The editor takes the full size of its container.

monaco.editor.create(document.getElementById("container"), {
	value: "function hello() {\n\talert('Hello world!');\n}",
	language: "javascript"
});

=======================HTML
<div id="container" style="height:100%;"></div>

=======================END




== Editor basic options
=======================JS
// Through the options literal, the behaviour of the editor can be easily customized.
// Here are a few examples of config options that can be passed to the editor.
// You can also call editor.updateOptions at any time to change the options.

var editor = monaco.editor.create(document.getElementById("container"), {
	value: "// First line\nfunction hello() {\n\talert('Hello world!');\n}\n// Last line",
	language: "javascript",

	lineNumbers: false,
	roundedSelection: false,
	scrollBeyondLastLine: false,
	readOnly: false,
	theme: "vs-dark",
});
