Answer 1

To check if element is visible we need to use element.isDisplayed(); But if we need to check for presence of element anywhere in Dom we can use following method

public boolean isElementPresentCheckUsingJavaScriptExecutor(WebElement element) {
        JavascriptExecutor jse=(JavascriptExecutor) driver;
        try {
            Object obj = jse.execute("return typeof(arguments[0]) != 'undefined' && arguments[0] != null;",
                    element);
            if (obj.toString().contains("true")) {
                System.out.println("isElementPresentCheckUsingJavaScriptExecutor: SUCCESS");
                return true;
            } else {
                System.out.println("isElementPresentCheckUsingJavaScriptExecutor: FAIL");
            }

        } catch (NoSuchElementException e) {
            System.out.println("isElementPresentCheckUsingJavaScriptExecutor: FAIL");
        }
        return false;
    }
