Java in JavaScript does not correspond to any relationship with Java programming language.
Explanation:
The prefix Java in Javascript is there for historical reasons.
The original internal name of Javascript when it was created by Brendan Eich at Netscape was Mocha. This was released to public as Livescript in 1995. The name Livescript was eventually changed to Javascript in Netscape Navigator 2.0 beta 3 release in December 1995 after Netscape entered into an agreement with Sun Microsystem. The primary purpose of change of name seemed to be as a marketing aid to benefit from the growing popularity of Java programming language at that time.
