Although the new language and its interpreter implementation were called LiveScript when first shipped as part of a Navigator beta in September 1995, the name was changed to JavaScript for the official release in December. Netscape management soon decided that the best option was for Eich to devise a new language, with syntax similar to Java and less like Scheme or other extant scripting languages. They pursued two routes to achieve this: collaborating with Sun Microsystems to embed the Java programming language, while also hiring Brendan Eich to embed the Scheme language. There was a desire in the burgeoning web development scene to remove this limitation, so in 1995, Netscape decided to add a scripting language to Navigator. ĭuring these formative years of the Web, web pages could only be static, lacking the capability for dynamic behavior after the page was loaded in the browser. The lead developers of Mosaic then founded the Netscape corporation, which released a more polished browser, Netscape Navigator, in 1994. Accessible to non-technical people, it played a prominent role in the rapid growth of the nascent World Wide Web. The first web browser with a graphical user interface, Mosaic, was released in 1993.
The ECMAScript standard does not include any input/output (I/O), such as networking, storage, or graphics facilities. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM). It is multi-paradigm, supporting event-driven, functional, and imperative programming styles. It has dynamic typing, prototype-based object-orientation, and first-class functions. JavaScript is a high-level, often just-in-time compiled language that conforms to the ECMAScript standard.

All major web browsers have a dedicated JavaScript engine to execute the code on users' devices. Over 97% of websites use JavaScript on the client side for web page behavior, often incorporating third-party libraries. JavaScript ( / ˈ dʒ ɑː v ə s k r ɪ p t/), often abbreviated JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS.

This might indicate they are waiting for some external resource (e.g. Number of threads sleeping on a monitor 13Ĥ0% of all threads are sleeping on a monitor.

It seems that the problem lies with the number of threads being created,threads waiting for monitor,locking and blocking.

Ok so I was able to learn how to use samurai,tda and the ibm thread dump tool. And is there any freeware preferably online that can analyze a. Im having a problem progressing with the analysis because it doesn't have the state of the thread and what code is being executed unlike the sample thread dumps that I've seen on the web.
Waiting on condition JNI global references: 1182 It pointed to the thread with nid 0x4974. I used jstack to get a thread dump of the PID with the highest cpu utilization.
