JavaScript is the most widely used programming language in the world, but that popularity comes with tradeoffs. JavaScript is accessible, flexible, and everywhere, yet increasingly fragile at scale.
The origins of JS trace back to Netscape’s rushed creation of a scripting language for web browsers, branded as JavaScript despite no relation to Java, and now Oracle has control of the Java AND JavaScript trademarks through their acquisition of Sun Microsystems… despite not actively developing products under the JavaScript name.
Modern JavaScript development is shaped by npm dependency sprawl, frequent CVE vulnerabilities, and ongoing supply-chain security risks. Incidents like the left-pad outage, NoIndex tag issues, and security exploits exposed how tiny JS packages can break production systems worldwide. Continuous framework churn from jQuery to Angular, React, Vue, and Svelte means many JavaScript codebases age quickly and require regular rewrites.
The ecosystem also highlights the limits of JavaScript’s weak typing, driving widespread adoption of Microsoft’s TypeScript and raising questions about type coercion, compiler performance and scalability. While Node.js remains popular for backend development due to its massive ecosystem, performance-critical systems increasingly rely on native C++ code or other compiled languages.
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.
Learn more →Cable / DSL
Best for fixed locations. Different network, so outages rarely overlap.
Learn more →Second Starlink
Adds redundancy and throughput for remote sites or heavy usage.
Learn more →Speedify bonds any two connections into one — automatic failover, more speed, no dropped calls.
