What is the difference between location.href = url and location.assign(url) ? Is it something in JavaScript memory consumption? Is there any official recommendation to use?
I consider the location.assign more elegant and readable, but I think it consumes more memory.
There is no difference - except that href is a property, so it also allows you to read its value, whereas the assign method only allows setting this value (and therefore loading a new page).
When you use the location.assign it loads that content from the url, but when you use the location.href it works like a traditional link, so it's best to do anchor with href:
location.href = "#top";
And to load a new page location.assign:
location.assign("https://www.pagina.com");

URLUtils.href
It is a DOMString that contains the entire URL.
Location.assign ()
Loads the resource in the URL provided as a parameter.
