Hey! @sudheerj can you check the PR i have made

[sudheerj]

@Vedavyasa21 Thanks for PR. This question is quite interesting. Please make the variable names bit descriptive. Can you provide the answer as well?

[Vedavyasa21]

@sudheerj Yeah I have changed the variable names
Should I add the solution below the code or in the discription ?

[sudheerj]

@Vedavyasa21 Can you make it in a folder with a structure similar to https://github.com/sudheerj/javascript-interview-questions/tree/master/coding-exercise/throttle-function

[Vedavyasa21]
