Best Practice introduced 2019-04-29 18:13 UTC by Report Bug Copy Issue Report If you intend to check if the variable `self` is declared in the current environment, consider using `typeof self === "undefined"` instead. This is safe if the variable is not actually declared. Loading history... Comprehensibility introduced 2019-04-29 18:13 UTC by Report Bug Copy Issue Report Usage of the sequence operator is discouraged, since it may lead to obfuscated code. The sequence* or comma operator allows the inclusion of multiple expressions where only is permitted. The result of the sequence is the value of the last expression. This operator is most often used in `for` statements. Used in another places it can make code hard to read, especially when people do not realize it even exists as a seperate operator. This check looks for usage of the sequence operator in locations where it is not necessary and could be replaced by a series of expressions or statements. var a,b,c; a = 1, b = 1, c= 3; could just as well be written as: var a,b,c; a = 1; b = 1; c = 3; To learn more about the sequence operator, please refer to the MDN.

Complexity introduced 2021-01-06 08:33 UTC by Report Bug Copy Issue Report A for in loop automatically includes the property of any prototype object, consider checking the key using `hasOwnProperty`. When iterating over the keys of an object, this includes not only the keys of the object, but also keys contained in the prototype of that object. It is generally a best practice to check for these keys specifically: var someObject; for (var key in someObject) { if ( ! someObject.hasOwnProperty(key)) { continue; // Skip keys from the prototype. } doSomethingWith(key); } Loading history...

		0 ignored issues – show Coding Style Best Practice introduced 2019-04-29 18:13 UTC by Report Bug Copy Issue Report Curly braces around statements make for more readable code and help prevent bugs when you add further statements. Consider adding curly braces around all statements when they are executed conditionally. This is optional if there is only one statement, but leaving them out can lead to unexpected behaviour if another statement is added later. Consider: if (a > 0) b = 42; If you or someone else later decides to put another statement in, only the first statement will be executed. if (a > 0) console.log("a > 0"); b = 42; In this case the statement `b = 42` will always be executed, while the logging statement will be executed conditionally. if (a > 0) { console.log("a > 0"); b = 42; } ensures that the proper code will be executed conditionally no matter how many statements are added or removed.
