Monaco Editor Playground Code

// 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: 'class Program { \n\t public static void main(String[] args) { \n\t\t var myVar = "this is a var"; \n\t\t int myInt = 12; \n\t} \n}',
	language: "java",
});
