Non-Blocking Operations Javascript

• Non-blocking actions are operations that don't halt execution of the main thread.
• This means that while the action is in progress, the Javascript engine can continue processing other tasks.

Examples of non-blocking actions

• Fetching data from a server (fetch)
• Timer (setTimeout)
• Handling user interactions (like permissions)
• Using web workers:
  • Web workers allow javascript to run tasks in a separate thread which can improve performance & responsiveness
