The filter method in JavaScript is used to create a new array with all elements that pass the test implemented by the provided function. Common errors include:

Incorrect Callback Function: Ensure the function returns a boolean value for filtering.

Not Returning the Filtered Array: The filter method returns a new array, so make sure you store or use it correctly.

Empty or Undefined Array: If the array is undefined or empty, the filter method will not work as expected.
