Ok, if you get into Harvard, go to Harvard. Your opportunities in the long run should outweigh any sort of student loans you have to pay back. If you're going to NoName Private College that's 90% of the cost of Harvard, go to state school instead.
And apply to scholarships. Lots and lots of scholarships.
JavaScript is a dynamically-typed language. Parallelizing the type checking with bundling gives you the best of both worlds: the speed when writing in a dynamic language and the type safety that comes with a static-typed language. For me, I like to write my code and not too concern myself with types until I’m close to committing; that’s when I fix type errors.
