What is the best way to streamline these two JavaScript lines and eliminate redundancy?

In order to address an issue, I implemented the following two lines of code:

MyString = div.getAttribute('data-type') || div.getAttribute('data-id');
MyString = MyString.replace('RemoveThis', '');

Although the code is functional, I noticed that I am repeatedly using the variable MyString. I attempted to condense it with this snippet:

MyString = div.getAttribute('data-type') || div.getAttribute('data-id').replace('RemoveThis', '');

Unfortunately, the condensed code did not work as expected.

Do you have any suggestions on how I can avoid repeating MyString?

Additionally, would the proposed solution be approved in a code review?

Answer №1

This type of repetition can actually be quite helpful because it enhances the readability and maintainability of the code.

However, to follow your method, you need to ensure that there are brackets surrounding 

div.getAttribute('data-type') || div.getAttribute('data-id')

MyString = (div.getAttribute('data-type') || div.getAttribute('data-id')).replace('RemoveThis', '');

An even better approach would be to improve the formatting a bit as well...

MyString = (div.getAttribute('data-type') || div.getAttribute('data-id'))
             .replace('RemoveThis', '');

Nevertheless, I still prefer the original version!
