JAVASCRIPT Questions and Answers

Mention what is the disadvantage of using innerHTML in JavaScript?

If you use innerHTML in JavaScript the disadvantage is

  • Content is replaced everywhere
  • We cannot use like “appending to innerHTML”
  • Even if you use +=like “innerHTML = innerHTML + ‘html’” still the old content is replaced by html
  • The entire innerHTML content is re-parsed and build into elements, therefore its much slower
  • The innerHTML does not provide validation and therefore we can potentially insert valid and broken HTML in the document and break it
