From The Free On-line Dictionary of Computing (30 December 2018) :

      (Formerly "LiveScript") Netscape's simple,
     cross-{platform, web scripting language, only
     very vaguely related to Java (which is a Sun trademark).
     JavaScript is intimately tied to the web, and
     currently runs in only three environments - as a server-side
     scripting language, as an embedded language in
     server-parsed HTML, and as an embedded language run in web
     browsers where it is the most important part of DHTML.
     JavaScript has a simplified C-like syntax and is tightly
     integrated with the browser Document Object Model.  It is
     useful for implementing enhanced forms, simple web
     database front-ends, and navigation enhancements.  It is
     unusual in that the scope of variables extends throughout
     the function in which they are declared rather than the
     smallest enclosing block as in C.
     JavaScript originated from Netscape and, for a time, only
     their products supported it.  Microsoft now supports a
     work-alike which they call JScript.  The resulting
     inconsistencies make it difficult to write JavaScript that
     behaves the same in all browsers.  This could be attributed to
     the slow progress of JavaScript through the standards bodies.
     JavaScript runs "100x" slower than C, as it is purely
     interpreted ({Java runs "10x" slower than C code).
     Netscape and allies say JavaScript is an "open standard" in
     an effort to keep Microsoft from monopolising web software
     as they have desktop software.  Netscape and Sun have
     co-operated to enable Java and JavaScript to exchange
     messages and data.
