# Configuring JSLint Validation

JSLint looks for a variety of coding errors, including undesirable or ambiguous constructs which it considers to be bad practice. JSLint will report only the first error it finds, and because it makes no distinction between blocking errors and complaints about coding style, JSLint errors are reported as warnings in yellow. JSLint doesn't come shipped with ATF, so it needs to be downloaded and configured.

1. Download JSLint

- Go to the URL, http://www.jslint.com/fulljslint.js
- Save the page as jslint.js

2. Define the location of JSLint using the preference pages.

- From the Window menu item open the ATF preference page for defining JavaScript Validation

- Window>>Preferences>>ATF>>JavaScript Validation
- Specify the location of JSLint - See Example Below
