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

Question

This question already has an answer here:

• Expected an assignment or function call and instead saw an expression 4 answers
• Why does jshint not recognize an assignment as an expression? 8 answers

I have the following line:

imageUrl && (data.imageUrl = imageUrl);

For this line, JSHint complains:

 Expected an assignment or function call and instead saw an expression.

I understand the warning, but I want to disable it. I can’t find the way how to do it. Any idea?

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.
