This is the last article in the expression series from simple to deep, but recently the team has been busy and never been busy! However, if you like expressions, please rest assured that some basic principles of Javascript are common in your work, so I decided to spend some time organizing the basic knowledge and sharing it with you. I was planning to write an article at the beginning, but later I wrote it and found more and more articles. So I decided to write a series. All content in this seri

A static variable is created before the program runs and always exists throughout the execution of the program. 2
