The need to manipulate strings comes up quite often, whether it's to validate user-provided values or transform text into structured data that can be used programmatically. Most often, we'll reach for regular expressions to accomplish this task, but sometimes there's a better solution to the problem: parser combinators.

Despite the general resistance towards time trackers, time and proper use proved them important. Both companies and employees realized how beneficial time trackers can be both for the company and for personal use.

As we mentioned in the previous article, at NodeSource, we are dedicated to observability in our day-to-day, and we know that a great way to extend our reach and interoperability is to include the Opentelemetry framework as a standard in our development flows; because in the end our vision is to achieve high-performance software, and it is what we want to accompany the journey of developers in their Node.js base applications.

Conceptually, a paradigm is a system of concepts and practices that reflect the current state of our understanding of the field. In general, a programming paradigm refers to a style, way, or classification of programming. Programming languages are used in order to solve problems.

One major reason for digging into API and product analytics is to be able to easily identify trends in the data. Of course, trends can be very tough to see when looking at something like raw API call logs but can be much easier when looking at a chart aimed at easily allowing you to visualize trends. Enter the Time Series chart.
