Can't run this code

Welcome, Shubham.

It is likely there is an issue with your personal environment. That is:

  • An old browser/incompatable browser (the latest stable release of Chrome is recommended for the fCC curriculum)
  • A browser extension is affecting the JavaScript on the page - disable browser extensions

It is difficult to help based off of a screenshot of code. For future posts, please include more information, in order to get more useful help:

  • Provide formatted code (place code between backticks) as such:
``` <- These are backticks
// Code can go here
```
  • Provide a link to the relevant challenge/problem
  • Take the time to fill out the body of posts to include as much information as necessary.

For future posts, if you have a question about a specific challenge as it relates to your written code for that challenge, just click the Ask for Help button located on the challenge. It will create a new topic with all code you have written and include a link to the challenge also. You will still be able to ask any questions in the post before submitting it to the forum.

Thank you.

please provide your code, not a screenshot

When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
