cookie1 = value; cookie2 = value; If you want to find the value of one specified cookie, you must write a JavaScript function that searches for the cookie value in the cookie string. JavaScript Cookie Example In the example to follow, we will create a cookie that stores the name of a...
Method 4: Using the some() method to check the array: The working of the some() method is almost the same as that of the find(). But the some() method returns a boolean value "true" if it checks and finds the value is present in the array else returns false. ...
