You're running the test against the wrong variable. In the below:

JavaScript

var data1 = /learning+\s+html+/g.test(data1);

You're calling .test(data1) which is testing against a variable which doesn't exist yet. You need to pass the value variable into this instead:

JavaScript

var data1 = /learning+\s+html+/g.test(value);

The regular expression might not be correct too, but I'm sure you will work this out. There are online regular expression evaluators[^] which can help with building the right expression.
