Function startTimer has a Cognitive Complexity of 7 (exceeds 5 allowed). Consider refactoring. Open
A1.startTimer = function(timerExpirationField, timerDisplayField, expiredCallback) {
var timerExpiresAt;
var handler;
if (timerExpirationField.length < 1) { return; } // field not present = order is done- Read upRead up
Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

- Exclude checks
disallow unnecessary semicolons (no-extra-semi)
Typing mistakes and misunderstandings about where semicolons are required can lead to semicolons that are unnecessary. While not technically an error, extra semicolons can cause confusion when reading code.
Rule Details
This rule disallows unnecessary semicolons.
Examples of incorrect code for this rule:
/*eslint no-extra-semi: "error"*/
var x = 5;;
function foo() {
// code
};Examples of correct code for this rule:
/*eslint no-extra-semi: "error"*/
var x = 5;
var foo = function() {
// code
};When Not To Use It
If you intentionally use extra semicolons then you can disable this rule.
