As a web software engineer, I can advise a few combinations of a strong Front-End tech build to have fewer limits when building your Startup.
So what I generally use?
As you can see Bootstrap is here, I use it in the case when I need UI now and it’s not so important to build a completely custom Front-End from scratch.
But why jQuery here? Well, because Bootstrap needs it for modal windows, etc… So everything that goes with JavaScript…
