Expected an assignment or function call and instead saw an expression

I'm totally cool with this JSLint error. How can I tolerate it? Is there a flag or checkbox for it?

You get it when you do stuff like: 

v && arr.push(v);

as opposed to: 

if (v) {
    arr.push(v);
}

Both do the same exact thing. If you put: 

window.test = function(v) {
    'use strict';
    var arr = [];
    if (v) {
        arr.push(v);
    }
    return arr;
};

into the minifier it minifies down to this anyway:

window.test=function(a){var b=[];a&&b.push(a);return b};
Solution

  • I don't think JSLint has an option to turn that off.

    JSHint (a fork with more options) has an option for it, though: The expr option, documented as "if ExpressionStatement should be allowed as Programs".
