In the JSONP usage pattern, the URL request pointed to by the src attribute in the <script> element returns JSON data, with JavaScript code (usually a function call) wrapped around it. This "wrapped payload" is then interpreted by the browser. In this way, a function that is already defined in the JavaScript environment can manipulate the JSON ...
The final release of JSR 223 happened on December 11, 2006. The specification, however, was withdrawn later on December 13, 2016 after a Maintenance Review Ballot, [1] where it was decided that this functionality would be included as an integral part of Java 9 and onward.
As explained by Douglas Crockford in his talk titled The JavaScript Programming Language on YUI Theater, [Microsoft] did not want to deal with Sun Microsystems about the trademark issue, and so they called their implementation JScript. A lot of people think that JScript and JavaScript are different but similar languages. That's not the case.
Opcode abbreviated from operation code is the portion of a machine language instruction that specifies the operation to be performed. Base instructions form a Turing-complete instruction set. Object model instructions provide an implementation for the Common Type System .
Nashorn is a JavaScript engine developed in the Java programming language originally by Oracle and later by the OpenJDK Community. It relies on the support for dynamically typed languages on the Java Platform (JSR 292) (a concept first realized in the experimental Da Vinci Machine and a standard part of Java 7 and later.)
The format makes no distinction between integer and floating-point. JavaScript uses IEEE-754 double-precision floating-point format for all its numeric values (later also supporting BigInt [19]), but other languages implementing JSON may encode numbers differently. String: a sequence of zero or more Unicode characters.
