Why does AngularJs re-execute code?

Question

Angular

On the site, all the code in the controllers began to be executed twice, before this was not the case.
A simple example: we write console.log('hello word'), when the site loads, the message in the console displays twice.
Why can this be?!

Answer 1

do you have a router? Which?

Answer 2

Angular itself works once, and the second time a crookedly written directive can work, which compiles / binds the DOM without notifying the kernel about it.
You also need to check if bootstrap is called twice.
