TODOs in javascript files not showing up in Task list

Question

For some reason the TODO Tags i added to my .js files are not showing up inside the Tasks View. I've already made sure, that the "TODO" tag itsself is set under Task Tags for javascript but thei're still not showing up in the list. I've made a filter for the view to show all Tasks in the working set i'm using but nothing is there.

Answer 1

nitind's answer is perfect. I would like to make it comprehensive.

Right click the project & select properties. In 'Builders' , select 'JavaScript Validator'.

Similarly, to parse tasks in HTML, CSS & XML files, goto Preferences->General->Editors->Structured Text Editors->Task Tags and click 'Enable searching for Task Tags'
