Classic functions are easy to read and write, but if you nest them in other functions and call them, the whole function becomes a bit verbose and confusing. At this point, you can use the arrow function to abbreviate:

Function sayHello (name) {console.log ('Hello', name);} setTimeout (function () {console.log (' Loaded')}, 2000); list.forEach (function (item) {console.log (item);})

Abbreviated as:

SayHello = name = > console.log ('Hello', name); setTimeout () = > console.log (' Loaded'), 2000); list.forEach (item = > console.log (item)); above is all the content of the article "how to abbreviate Arrow functions in JavaScript".
