Disable JSHint warning: Expected an assignment or function call and instead saw an expression [duplicate]

Answer 1

If it really is just that one line

imageUrl && (data.imageUrl = imageUrl); // jshint ignore:line

I am a fan of writing code so it doesn't produce warnings, though, even if this means taking special action to do so. So I'd prefer

if (imageUrl) data.imageUrl = imageUrl;

Answer 2

Include a /* jshint expr: true */ comment in your Javascript.
