why airbnb is using yet semicolons?

I've read moderns apps don't use anymore semicolons, maybe in the future airbnb style too ? maybe with https://standardjs.com/ ?

I'm not sure where you've read that, and it's quite false. Using semicolons is something the vast majority of JS devs do, despite the recent rise in usage of "standardJS" - something that is not actually a standard, nor something that aligns with what the majority of JS devs do in a number of ways.

The professional and modern thing to do is not to omit optional tokens, but to always use them, since explicit > implicit.

Additionally, not using semicolons can rise a series of unexpected bugs, take this line of code for example:

var obj = {n: 1};
var a = obj
[a].forEach(item => console.log(item)) //error

This results in an error, although the expected is to log the obj.

I started a new project without using semicolons and after a few days I switched back to using semicolons for a simple reason: With semicolons, you get better parser, and in case of TypeScript, compiler messages.

Let's say you have forgotten a closing parenthesis on one line and went to the next line. The compiler may tell you that it expects a comma at the end of the line for an optional parameter, but if you closed the line with a semicolon, it will tell you that it expects a closing parenthesis. Also, I find it easier to skim through the code when lines are ended with semicolons.
