Ecmascript Engine Has Reported An Error

29, 200740 0 0 0 The web has become the primary global computing platform tying together hundreds of millions of sites. In the eight years since the release of the ECMAScript Language Specification what is ecmascript 2015 3rd Edition (ES3), ECMAScript (commonly known as JavaScript™ or JScript ™) has how to use rhino javascript engine grown in importance as one of the key technologies of the web.
Es2015 Browser Support
The specification of ECMAScript has been stable for eight years. In many ways, this stability was probably an essential enabler for the emergence and broad adoption of

However, today’s ES3 standard does not capture all the de facto compatibility conventions reached by eight years of this stability - the compatibility so essential to the success of rich web applications. For rich web applications to be successful, JavaScript must function identically on all browsers. The developer of a JavaScript-based web application es2015 support does not get to choose what implementation will run their application; the user implicitly chooses that when they choose their preferred browser. Strong implementation conformance, then, across browser-based implementations is fundamental. Let me give you a few examples of the lack of such conformance: Did you know that Custom properties that shadow [[DontEnum]] properties on Object.prototype are not enumerated using for-in in IE? Consequently, it is not possible to transfer them from one object to another using for-in. Consider the following script where toString is shadowed on cowboy. script function cowboy() { this.toString = function () { return "cowboy"; } this.shoot = function () { return "bang!"; } } var p = new cowboy(); document.write("Enumerable properties:"); for (var i in p) { document.write(" ", i); } var res = p.propertyIsEnumerable("toString"); document.write("
propertyIsEnumerable(\"toString\"): ", res); res = p.hasOwnProperty("toString") document.write("
hasOwnProperty(\"toString\"): ", res); How about the case where FireFox implements additional properties (and that could cause unexpected results)? script var x = {}; x.__proto__ = 3; document.write(x.__proto__); Try these on you
