JavaScript is built into all modern browsers by default. JavaScript only exists inside the browsers context, so unlike Python or Java, there's nothing else needed on your system.
If you're getting error messages about your browser's JavaScript, it's time to update your browser to a newer version.
I don't know if there is a shorter way to check for sure, besides JavaScript not working on sites, but just follow the instructions for whatever browser you are on.
Chrome: Wrench icon (option menus) > Options > Under The Hood > Content Settings > Check if "Allow all sites to run JavaScript" is enabled
Firefox: Click on the Firefox button (Tools for Windows XP) > Content > Check if JavaScript is enabled.
(For Firefox you may have to open the Advanced menu and to see what settings are enabled in JavaScript)
Safari: Choose Safari > Preferences > Click on Security > See if Enable JavaScript is checked
Internet Explorer: Tools > internet Options > Click on Custom Level > Scroll to Scripting section > Check if Active Scripting is enabled.
Opera: Tools > Preferences > Advanced > Content > Check if Enable JavaScript is checked.
This answer is to check for the users. I'm sorry if you are looking to see if it is enabled in the actual code. However if it is disabled and you want to see if it is from your code, The obvious answer would be if the checker for JavaScript ran or not :).
