Which is the subset that transforms web content into secure modules that can be safely hosted on a web page?

Solution(By Examveda Team)

Caja is Google’s open-source secure subset. Caja (Spanish for “box”) defines two language subsets. Cajita (“little box”) is a narrow subset like that used by ADsafe and dojox.secure. Valija (“suitcase” or “baggage”) is a much broader language that is close to regular ECMAScript 5 strict mode (with the removal of eval()). Caja itself is the name of the compiler that transforms (or “cajoles”) web content (HTML, CSS, and JavaScript code) into secure modules that can be safely hosted on a web page without being able to affect the page as a whole or other modules on the page.
