Disallow Parens Around Functions (no-wrap-func)
Replacement notice: This rule was removed in ESLint v1.0 and replaced by the no-extra-parens rule, when configured in the "functions"
mode.
Although it’s possible to wrap functions in parentheses, this can be confusing when the code also contains immediately-invoked function expressions (IIFEs) since parentheses are often used to make this distinction. For example:
var foo = (function() {
// IIFE
}());
var bar = (function() {
// not an IIFE
});
Rule Details
This rule will raise a warning when it encounters a function expression wrapped in parentheses with no following invoking parentheses.
The following patterns are considered warnings:
var a = (function() {...});
The following patterns are considered okay and do not cause warnings:
var a = function() {...};
(function() {...})();
