The OP asked for a JavaScript solution, not a framework/library.

@mattpark22 While I understand what you're getting at, a javascript library is still javascript. I could rip out just the relevant pieces of the library and present those as a code solution. OP would have an answer that was javascript, in the sense that you mean it, but would be unaware of a (possibly) acceptable, general purpose solution. Also, adding 30 minutes is not nearly as trivial as most of the answers make it sound, as there are a lot of edge cases not handled by the Date object. For example, the most popular answer breaks when crossing DST boundaries.

@Ouroborus—libraries should not be the only solution provided if the OP has not asked for a library in the OP or tags. Otherwise, answers can become just a litany of ways to do something in different libraries and the OP is left no wiser to their actual issue (which in this case is fairly trivial to solve).

@RobG No one's suggesting that only library solutions should be provided. OP can't specifically ask for a library as that would cause the question to be off-topic. Asking "How do I do it with JavaScript?" could be construed as specifying that this is specific to javascript (asking for a solution in a specific language as opposed to asking for a raw code solution) especially given that this detail is repeated in the title and the tags.
