double quotes

Using Syncfusion Angular and JavaScript controls makes front-end web development a piece of cake. Each component has many properties that can be configured as per your desire, methods that can be used to interact with the element, and a lot of events that trigger at different stages, which makes modifying your components according to the state of the application an easy task. Also, their support is amazing! They always offer a sample working project, which makes it very simple to solve your question about your code.
