Synchronous JavaScript

Whenever a web page tries to load, your browser looks for directions within the site’s code, which almost always include JavaScript tags. The tags control what content is delivered to each visitor and also impact a website’s speed in regard to loading times. JavaScript has two forms, “Synchronous JavaScript” and “Asynchronous JavaScript.”

“Synchronous JavaScript” is read by your browser as its name suggests: in a synchronous order. Logically, this may sound great, but in reality, it means slower loading times as the next action can’t begin until the previous action has completed. Slower loading times may cause companies visitor loyalty and revenue gains in a fraction of a second.
