Where in the project to place a folder for different functions?

Question

JavaScript

In a project (vue) there was a need to use the same functions in different places. Is there any generally accepted solution for putting things like this somewhere?

Now I'm placing it in the mixins folder, but this is clearly not the most correct solution. these functions are used not only in components, but also in other places (store, etc.)

Answer 1

In which folder should I put common functions that I export for import into various components?
