Here are a few things every JavaScript developer should know

1. JavaScript and Java are completely different languages, both in concept and design.
2. JavaScript was invented by Brendan Eich in 1995, and became an ECMA standard in 1997.
3. ECMA-262 is the official name of the standard. 
4. ECMAScript is the official name of the language.
5. The abbrivation of ECMA is European Computer Manufacturer's Association.
6. JavaScript was first known as LiveScript when it first shipped in beta releases of web browser Netscape Navigator 2.0 in September 1995, but it was renamed JavaScript when it was deployed in the Netscape Navigator 2.0 beta 3 in December.
7. Web pages are not the only place where JavaScript is used. Many desktop and server programs use JavaScript. Node.js is the best known. Some databases, like MongoDB and CouchDB, also use JavaScript as their programming language.
8. ECMA-262 is managed and evolved by Ecma's Technical Committee 39 (TC39). 
9. Its members are companies such as Microsoft, Mozilla, and Google, which appoint employees to participate in committee work; examples include Brendan Eich, Allen Wirfs-Brock (editor of ECMA-262), and David Herman. 
10. To advance the design of ECMAScript, TC39 hosts discussions on open channels (such as the mailing list es-discuss) and holds regular meetings.
