What is the disadvantages using innerHTML in JavaScript?
Answer:
► If you use innerHTML the content is replaced everytime.
► We cannot use like 'appending to innerHTML'.
► Even if we use += like "innerHTML = innerHTML + 'html'" then also the old content is replaced by html.
► If we use innerHTML then the entire innerHTML content is re-parsed and build into elements. Therefore it's much slower.
► The innerHTML doesn't provide validation and therefore we can potentially insert invalid and broken HTML in the document and break it.
