Browsers support JavaScript, and Node.js supports it too. I want to know if there any syntax difference between them?

JavaScript is a simple programming language that runs in any browser JavaScript Engine. Whereas Node JS is an interpreter or running environment for a JavaScript programming language that holds many excesses, it requires libraries that can easily be accessed from JavaScript programming for better use.
js uses Google's V8 engine to provide JavaScript runtime and employes its own event loop using the libuv library (written in c). Node follows the same callback approach like Web APIs and works in a similar fashion as the browser.
Node uses the same JS "engine" that runs chrome. An engine in this case, is a piece of software that compiles, or "translates" your JS code into machine code; or the 0s and 1s your computer can understand.
Node uses Google V8, which implements the ECMAScript standard (link to non official annotated copy).
How it differs from browsers will depend on which browser (and version) you're talking about.
For example, Mozilla browsers implement JavaScript (which is an implementation and superset of ECMAScript).
JavaScript includes:
for each - in loopslet expressions...among other enhancements that utilize non ECMAScript standard syntax. These are all part of JavaScript, but not currently part of the ECMAScript standard.
(Of the 4 items listed, the last 3 are proposals for the next ECMAScript version.)

No. The Syntax is exactly the same. There are differences in the apis however. The standard browser dom is not available in node but it has additional apis found at nodejs.org. Any syntax differences are due to quirks in browsers.
