Imagine a world where JavaScript, the backbone of 49,501,698 websites, takes a mere 5-second break. You might think it’s inconsequential, but the ripple effects could be more significant than you’d imagine.

In just a second, the internet processes a million Google searches and 100,000 YouTube video views. The question is, what happens if JavaScript were to suddenly stops working?

Domino Effect: Stock Markets and Beyond

At first glance, a 5-second disruption may seem negligible to an individual user — a mere error message asking to enable JavaScript. However, the global consequences could be staggering.

The world’s stock markets, including giants like the New York Stock Exchange, heavily rely on JavaScript for trade execution.

In the blink of an eye, the functionality of stock market platforms could be compromised, potentially causing chaos in the world of trading where every second counts.

Online Payments and Social Media Standstill

Ever wondered about the fate of internet payments and social media during a JavaScript hiccup? Without JavaScript, the smooth functionality of payment gateways could be compromised, disrupting the seamless flow of online transactions.

Social media platforms, especially Twitter, would become paralyzed. Posting a tweet, dependent on JavaScript, would likely yield no results. Even the simple act of searching on Google would be futile without JavaScript.

The 99% Dilemma: Websites in Limbo

JavaScript is the lifeblood of the internet, powering 99% of websites, including popular ones like Canva, Twitter, Figma, YouTube, and GitHub. Without JavaScript, these platforms would display blank pages, rendering them useless.

For the 1% of internet users who deliberately disable JavaScript, the impact could be more significant than anticipated.

This small percentage, representing visits rather than users, holds the potential to disrupt web app functionality, causing frustration and potential user churn.

JavaScript: The Brain of Modern Websites

Most contemporary websites are constructed on JavaScript frameworks, making it the virtual brain behind their functionality. Intentionally or unintentionally blocking JavaScript could cripple almost every interactive feature on a website.

I read an awesome blog about JavaScript availability, check this:

So, the next time JavaScript takes a break, perhaps it’s an opportunity to step outside, take a breath, and appreciate the web of functionality. After all, thanks to JavaScript, you can even read this blog.
