in javascript, the `length` property of an array indicates the number of elements in the array. when an array has a length of 0, it means that the array is empty, i.e., it does not contain any elements.

here is an informative tutorial about javascript array length being 0 but not empty:

1. *creating an empty array with a length of 0*
you can create an empty array with a length of 0 by simply initializing an array with empty square brackets `[]`:



2. *checking if the array is empty*

3. *adding elements to the array*
you can add elements to the array even if its length is 0. this will increase the length property accordingly:



4. *removing elements from the array*

5. *conclusion*
in javascript, an array with a length of 0 is considered an empty array, even though technically it still exists as an array object. you can manipulate the array by adding or removing elements, and its length property will reflect those changes.

i hope this tutorial helps you understand how javascript arrays with a length of 0 can be empty but not truly empty in terms of being an array object. let me know if you have any questions or need further clarification!
