4. The History of JavaScript
The World Wide Web was originally a bunch of pages linked together by hyperlinks
Soon people wanted more interaction and so Netscape (an early browser vendor) asked Brendan Eich to develop a new language for their Navigator browser
This needed to be done quickly because of the intense competition between Netscape and Microsoft to be first to market, and Eich managed to create a prototype language in just ten days
The new language was originally called LiveScript, but was hastily rebranded as JavaScript so that it could benefit from the publicity that the Sun Microsystem’s Java language was attracting at the time

5. The History of JavaScript
This name has often caused some unfortunate confusion, with JavaScript often thought of as a lighter version of Java; the two languages are unrelated, although JavaScript does share some syntax with Java
JavaScript made its debut in version 2 of Netscape’s Navigator browser in 1995
The following year, Microsoft reverse-engineered JavaScript to create their own version, called JScript to avoid copyright issues with Sun who owned the Java trademark and had licensed it to Netscape
Remember:
JavaScript is a client side, interpreted, & loosely typed scripting language which runs on browser (client)

6. The History of JavaScript
Scripting Languages
Interpreted high-level languages that are translated into machine code at run time are often referred to as scripting languages
They typically run slower than compiled languages
Although interpreters are becoming more and more sophisticated, increasingly blurring the line between compiled and interpreted languages
The ECMAScript standard can be difficult to interpret in places, so the implementations of JavaScript can vary in assorted JavaScript engines
This is why some web browsers behave differently when running JavaScript programs
