brackets.io throws unnecessary errors

Hi, any idea why brackets.io is throwing me unnecessary errors while this basic code seems to be fine and working?

JSLint 'prompt' was used before it was defined. var a = prompt('write something'); document.write can be a form of eval. document.write(a);

ESLint ERROR: 'prompt' is not defined. [no-undef] var a = prompt('write something'); ERROR: 'document' is not defined. [no-undef] document.write(a);

Not sure what does this mean, and obviously I am pretty new to all this so thanks for patience.

Please show your whole code. The index and the js file too.

Code

Wrap your code with 3 backticks (```) on the line before and after. If you specify the language after the first set of backticks, that'll help us with syntax highlighting.

      ```html
      <p>This is code!</p>
      ```

I'm not a "brackets" user, but "prompt" is a function of a browser, so if your code is being executed in a server-side JavaScript engine, it would make sense that it is not defined. This would also be the case with "document".

The same thing would happen if you ran a program with "prompt" or "document" in it using node.js.
