Asynchronous programming in JavaScript leverages features like callbacks, promises and async/await to sidestep this issue by allowing other code to run in the meantime.

You can assign data to a structure, then use R commands to work with the resulting structure — to quickly extract basic statistical information, for example, or sort data.

So the world of programming became divided, roughly, into two tribes. If software needed to run fast or on a tiny chip in an embedded device, it was more likely to be written in C or C++.
