What is the matter with script-targeted URLs?
javascript, jshint, validation
Solution
`javascript:` URLs are part of 'eval is evil'.
In order to execute the `javascript:` URL, the browser must fire up a JS parser and parse the text of the URL. This is a slow and costly process.
Also, assembling `javascript:` URLs (or other strings that contain source code) is a tricky task which is prone to XSS vulnerabilities.
Finally, mixing code and URLs violates the separation of content and behavior (code).
Problem
I'm using JSHint, and it got the following error: ``` Script URL. ``` Which I noticed that happened because on this particular line there is a string containing a `javascript:...` URL. I know that JSHint complained that because the `scripturl` option is set, and since my codebase is quite large, I'll have to unset it for now. Still, I don't understood what is the issue of using script URLs?
