This I think really depend on the design of your system.
In angular/vue/react, the framework seem to have developed around the keyword this without an issue. I wonder why they have made this choice if this could be troublesome.
Yeah, but in react click handlers and other stuff most of the time need this, which leads to you either abusing class properties for arrow functions or having bind everywhere
I use React quite often. So, I use this a lot. I use arrow functions all the time, so every single this I use refers to the outer most instance, the component, every single time. Definitely a personal preference anyway :)
the only advantage that I could think of using this is the ability of reusing functions. Using the method suggested by my friend will create a new function instance for every object created. But if we use class, essentially we are using prototype, so all the methods will only be defined once. It makes a difference when we are creating the same instance many many times.
It completely shatter the prototype which is bad IMO. Your friend's method not only create a new function each time, but prevent any ineritance.
Also, it's not possible to supercharge Car's prototype.
The "this" keyword can be tricky, but avoiding it leaves you in a land without OOP.
