JSLint: Expected ‘return’ at column X, not column Y

January 17, 2013

I’ve been writing some Javascript using the default settings in Chocolat, tabs instead of spaces and each tab is equivalent to 2 spaces. Running most of my javascript files through JSLint is fine, but there were a few lines that were generating warnings, even though the spacing looked just fine.

if (validateCardRequestDidSucceed(stripeResponse) === false) {
    response.error("Stripe card request failed with unknown error")
    return
}

What’s wrong here? That spacing looks just fine to me. Turns out that the default settings in JSLint want spaces instead of tabs and 4 spaces per indentation. JSLint, by default, ignores tabbed indentation, but somehow that return had been indented with spaces.

Replacing the spaces with tabs cleared up the issue.

In other news, I should probably switch to 4-space indentation. I’m not picky about spacing and, all things being equal, I might as well stick with the JSLint conventions.
