 The `continue` statement terminates execution of the statements in the current iteration of the current or labeled loop, and continues execution of the loop with the next iteration. When used incorrectly it makes code less testable, less readable and less maintainable. Structured control flow statements such as `if` should be used instead.

 The comma operator includes multiple expressions where only one is expected. It evaluates each operand from left to right and returns the value of the last operand. However, this frequently obscures side effects, and its use is often an accident. Here are some examples of sequences:
 
 ```js
-var a = (3, 5); // a = 5
+let a = (3, 5); // a = 5
 
 a = b += 5, a + b;
