I'm trying to understand why this line invokes an error:

const value = 20 * 30;

error TS1008: Unexpected token; 'module, class, interface, enum, import or statement' expected.

any idea?

Which ECMAScript version are you using ? 5 or 6 ? - Alex
Please add more details - i.e. TypeScript version and a longer snippet which provides the error. - Martin Vseticka
Are you using Visual Studio ? If yes, did you update to the latest version of TypeScript (see visualstudiogallery.msdn.microsoft.com/…) - Alex
When running tsc version I get : Version 1.0.3.0 and when running where tsc I get: 1.0 and 1.7 versions. I added 1.7 in PATH variables - Dusty

Here is the solution:

Earlier on my machine I had installed Visual Studio 2015 Pro Edition. that had installed TypeScript 1.0.3.0. and added its path to system environment.

Now I used npm install -g TypeScript and it did install, however from command line, typing tsc --version was always giving 1.0.3.0.

I removed the older path from environment and then restarted code and it worked fine.

Better you check your versions and the solution might help.

It doesn't cause an error for me: https://jsfiddle.net/n0w1jt7b/

const value = 20 * 30; // 600

Be sure that all your versions are up-to-date.
