Both forms of storage are scoped to the document

This preview shows page 31 - 34 out of 55 pages.

Both forms of storage are scoped to the document origin so that documents with different origins will never share the stored objects. But sessionStorage is also scoped on a per-window basis. If a user has two browser tabs displaying documents from the same origin, those two tabs have separate sessionStorage data: the scripts running in one tab cannot read or overwrite the data written by scripts in the other tab, even if both tabs are visiting exactly the same page and are running exactly the same scripts.

What’s the difference between the <svg> and <canvas> elements?
The <svg> element is a container for SVG graphics. SVG has several methods for drawing paths, boxes, circles, text, and even bitmap images. SVG is a language for describing 2D graphics, but <canvas> allows you to draw 2D graphics on the fly using JavaScript. SVG is XML-based, which means that every element is available within the SVG DOM. You can attach JavaScript event handlers for an element. In SVG, each drawn shape is remembered as an object. If attributes of an SVG object are changed, the browser can automatically re-render the shape. Canvas is rendered pixel by pixel. In canvas, once the graphic is drawn, it is forgotten by the browser. If its position should be changed, the entire scene needs to be redrawn, including any objects that might have been covered by the graphic. * There is more to interviewing than tricky technical questions, so these are intended merely as a guide. Not every “A” candidate worth hiring will be able to answer them all, nor does answering them all guarantee an “A” candidate. At the end of the day, hiring remains an art, a science — and a lot of work.
