JavaScript is the most popular programming language in the world.
This page contains some examples of what JavaScript can do.
One of many HTML methods is getElementById().
This example uses the method to "find" an HTML element (with id="demo"), and changes the element content (innerHTML) to "Hello JavaScript":
document.getElementById("demo").innerHTML = "Hello Tutorialink";
JavaScript and Java are completely different languages, both in concept and design.
JavaScript was invented by Brendan Eich in 1995, and became an ECMA standard in 1997.
ECMA-262 is the official name. ECMAScript 6 (released in June 2015) is the latest official version of JavaScript.
