Utils or Helpers

When to use helpers and utils? Here is my rule of thumb.

• helpers are specific to a project and are not usually reused across different projects.
• utils, on the other hand, are used for general purposes and can be reused across multiple projects.

Consider the following example:

• The validatePassword function can be a helper. This is because the criteria for password validation can vary significantly across different projects, often depending on specific business requirements.
• A function like formatDate can be a utility. Because it offers functionality to format dates in various ways, making it suitable for different projects.
