the arrow function works as follows:

(args) => {
//your code here
}

where args is your arguments it’s also called the arrow function or anonymous function, it works just as any other function but it’s anonymous, you’ll find it very useful to use with .map(), .filter()…etc

you can assign it a name as follows:

let myfunction = (args)=>{
//yourcodehere
}
