4 ways of calling an API in Javascript.

I think all of them are incredibly similar, so I think it primarily depends on what else you're already using in your app/site.

For instance, if you're already using jQuery for other stuff, then just use jQuery $.ajax, rather than including yet another lib (like Axios etcetera).

If you're not using jQuery but "Vanilla JS" with a somewhat modern browser, then you might prefer "fetch" as it's natively supported by the browser (again, no need to load/include another lib).

Axios is a bit easier to use than "fetch", with way more baked-in features (which are however not that hard to emulate with "fetch") ... "fetch" is a little bit more low-level than Axios - but, Axios comes with a bundle size of 5KB gzipped.

XMLHttpRequest is a bit old-fashioned, "fetch" is its more modern and easier to use replacement.

So I think in most cases the choice would be between Axios and "fetch" (unless you happen to use jQuery).

jQuery should disappear soon hopefully so don't use that. XML http request is cute, so don't use that.That leaves fetch api or axios. Both work cross platform now. Btw, there are more libs available for http requests like superagent. Axios is by far the most popular though, infact its one of the most popular libraries in the whole npm ecosystem.
