Editor's Notes
- https://www.destroyallsoftware.com/talks/wat
- ECMAScript 3 was released in December 1999 and is the modern-day baseline for JavaScript
- Also, with the release of Microsoft Internet Explorer 5.0, Microsoft released the first version of XMLHttpRequest, giving birth to Ajax
- XML due to MSXML Also included XSLT for transforming data Both XML and XSLT mostly abandoned for JSON+JS
- DOJO slightly earlier MooTools slightly later

- http://blogoscoped.com/google-chrome/ Chrome actually for speed, retrofitted for minimal browser chrome/UI
- https://en.wikipedia.org/wiki/Private_browsing First one was Safari (yay Apple and privacy...)
- In December 2009, Google released beta versions of Chrome for OS X and Linux. Google Chrome 5.0, announced on May 25, 2010, was the first stable release to support all three platforms. https://gs.statcounter.com/browser-market-share#monthly-200901-201908
- Wow....see next graph... Blink once they had enough market share to want to control everything?

- Notable breakages https://en.wikipedia.org/wiki/Npm_(software)#Notable_breakages In March 2016, npm attracted press attention after a package called left-pad, which was a dependency of many popular JavaScript packages, was unpublished as the result of a naming dispute. Although the package was republished 3 hours later, it caused widespread disruption, leading npm to change its policies regarding unpublishing to prevent a similar event in the future. In February 2018, an issue was discovered in version 5.7.0 in which running sudo npm on Linux systems would change the ownership of system files, permanently breaking the operating system. In July 2018, the npm credentials of a maintainer of the popular eslint-scope package were compromised resulting in a malicious release of eslint-scope, version 3.7.2. The malicious code copies the npm credentials of the machine running eslint-scope and uploads them to the attacker. In November 2018, it was discovered that a malicious package had been added as a dependency to version 3.3.6 of the popular package event-stream. The malicious package, called flatmap-stream, contained an encrypted payload that steals bitcoins from certain applications. npm administrators responded by removing the offending package.
