'Missing semicolon' warning in Eclipse for JavaScript code

Question

Eclipse gives me the warning 'Missing semicolon' for line 4 of the following code:

const C = 'b';
function foo() {
    alert('x');
}

It does not for the following code:

//const C = 'b';
function foo() {
    alert('x');
}

For the following it gives me two warnings:

const C = 'b';
function foo() {
    alert('x');
};

Multiple markers at this line

Is there a way to make Eclipse ignore my lines with 'const'? Or is there another way to solve my problem?

I am using:

Eclipse IDE for JavaScript Web Developers.
Version: Indigo Service Release 1
Build id: 20110916-0149

There is only a proposed const in JavaScript. Use

var C = 'b';

Actually, there is a const apparently, but it is not supported by all browsers and would not be good to use for that reason.

The reason Eclipse is giving you the warning is that it does not recognize const which is a known bug in Eclipse.

Actually there's in a newer js version. const isn't supported by some browser but if you aren't going to target them it's ok to use the keyword. – Konstantin Solomatov Mar 01 '12 at 08:46

Yeah, just read that too. Nevertheless it would be bad practice to use const. – Asken Mar 01 '12 at 08:47

Updated the answer to reflect reality ;) – Asken Mar 01 '12 at 08:51
@Asken It depends and what we target. If we target node.js it's a good idea to use the keyword. – Konstantin Solomatov Mar 01 '12 at 09:01

You may disable some warnings in the preference menu:
