Overview

In an increasingly competitive business landscape, time is one of the most valuable assets for organizations to gain a significant advantage. In addition, many programmers are time-pressed to develop excellent web apps in a short time. However, coding and testing web applications, to say the least, are incredibly time-consuming. This is where Express comes in handy to simplify matters for programmers. Express.js is a popular Node.js framework that contributes to the faster and more efficient creation of server-side web applications. Simplicity, scalability, and flexibility are some of its notable characteristics, and since it's layered on top of Node.js, it delivers an equivalent performance.

Finding and onboarding talent matching the job-relevant criteria is arduous for hiring managers and employers. The prime contributors are a half-baked screening strategy and a flawed assessment methodology. Moreover, resume accomplishments do not indicate a person's technical competence, capability, or work readiness.
