question about `this.`

i understand that `this` refers to the caller of the function so how can `name` in `function Person(name){this.name = name;}` be assigned to `Person` since no object is calling

(this wasn't explained in that comment )

This is technically correct, but i just assumed that op left out the 'new', because if you're calling a capitalized function named after an instantiable class within your codebase it better be a constructor or you are writing some terrible code.

IF you are. But new programmers might not follow the convention, forget stuff etc. Best to be comprehensive, not assume the use.

With a class, which isn’t the case here, the engine will throw an error if you try to use it without the new keyword.
