H

hot start

A hot start refers to when your mini program's process is already running in the background. In a hot start, all the system does is bring the mini program's activity to the foreground. This makes it a lot faster than a cold start because the activity is already present in memory. So the system has no need to repeat the initialization.

HTML

HTML (HyperText Markup Language) is the most basic building block of web pages. It is a markup language that defines the meaning and structure of web content. HTML consists of a series of elements, which you use to enclose or wrap different parts of the content to make it appear a certain way or act a certain way.
