How does HTML5 use web workers, and why is this important?
One of the key responsibilities of a senior software engineer is maintaining their currency in newly developing technologies. Interviewers will ask you about techniques and methodologies associated with the latest software and development tools used in your profession. They want to make sure your knowledge of these is current, and you can employ them in your work if hired.
"The purpose of web workers within HTML5 is to run background scripts in a web application without impacting the user interface. This creates a multi-threading-like environment in JavaScript, which is a single-threaded application. Therefore, web workers is a useful technology to accelerate the performance of websites written in JavaScript."
You should anticipate questions like this and refresh your knowledge about these topics by reviewing vendor websites, technology blogs, and other sources of information before attending the interview. Conversely, you should also be familiar with legacy versions of the applications which the organization may still be using. Being knowledgeable about topics and both of these areas will help you perform well in the interview and likely lead to a job offer.
