JSHint忽略`！function（）{/ * ... * /}（）`模式

Question

How can I configure JS Hint to ignore JSHint ignore !function(){ /* ... */ }() pattern. Currently, it is throwing warnings for me to tell me it expects a statement or assignment. I expect this is due to !function converting the function into a function expression, which goes nowhere. I know I could do... var garbage = !function ... but I don't want to change the source code to please JS Hint, I want to tell JS Hint that it is ok to use an operator to coerce a function into an expression.

You can disable it. Put this at the beginning of the file or add the expr option to your .jshintrc configuration.

/*jshint expr:true */

This option allows any raw expression such as:

!function(){}();
a || b();
a ? b() : c();

You'd write it like this to avoid the warning:

(function(){}());
if (!a) b();
if (a) {
  b();
} else {
  c();
}
