v8

I don't know if this is a bug with Node or V8, but if I run the following code the node process leaks memory. The GC never seems to kick in and in a few seconds it's consuming >1GB of memory. This is unexpected behavior. Am I missing something? Here's the code: for(;;) { console.log(1+1); } Obviously, this is a little bit of a contrived situation, but I can see an issue with a long-running process that would never free memory. Edit: I tried both with v0.5.10 (unstable) and v0.4.12 (stable) and the unstable version performs a little bit better---the stable version just stops outputting to the

Recently I've fallen out of love with Perl as a cross-platform general purpose scripting language, and niether Python nor Ruby ever really appealed to me either. But I've been getting more and more comfortable with JavaScript in the browser, it's getting

V8 Date parser is broken: > new Date('asd qw 101') Sat Jan 01 101 00:00:00 GMT+0100 (CET) I can use fragile regular expression like this: \d{1,2} (jan|feb|mar|may|jun|jul|aug|sep|oct|nov|dec) \d{1,4} but it is too fragile. I cannot rely on new Date (issue in V8) and also moment cant help me because moment is getting rid off date detection (github issue-thread) . is there any workaround for broken v8 date parser? To be clear. We have Gecko and V8, both have Date . V8 has broken Date, Gecko has working one. I need the Date from in Gecko (Firefox). Update: It’s definitely broken parser https:/

Looking for template engine like HTML::Mason (or Mason), so what "compiles" source components into perl code, but instead of perl-code will "compile" components into JavaScript code and after run/execute them with Javascript::V8 perl module. Motivation: Looking for solution for safe template language, what can edit users without compromising the server security . JavaScript is full featured language so using it is probably better/faster than some "mini languages" like TT or similar. The best for me would be an extension (rewrite) of Mason for compiling into Joose/JavaScript instead of Moose

Unfortunately, after executing the project (build succeeds without issues), I get an exception related to missing j2v8_android_x86 library file. The issues occurs when trying to create V8 runtime: V8 runtime = V8.createV8Runtime(); The exception itself is: Caused by: java.lang.IllegalStateException: J2V8 native library not loaded. at com.eclipsesource.v8.V8.checkNativeLibraryLoaded(V8.java:86) at com.eclipsesource.v8

I see the incoming argument can be tested by IsArray(), but there isn't a ToArray(). How do you get access to its Length, and request elements by numeric index? Handle < Value > MyExtension ( const Arguments & args ) { Handle < Value > v = args [ 0 ]; if ( v -> IsArray ()) { // convert to array, find its length, and access its members by index... ? } ... } Must be missing something obvious here. Object can return all its properties, but that's not quite

I have been studying JavaScript algorithms and Big O for interviews. I was told that knowing the runtimes of built-in methods, such as Object.prototype.hasOwnProperty and Array.prototype.map , is important. What is a simple way to view the source code for these functions in node.js? I have a local copy of node.js, and I tried to search for these methods in my text editor, but it's not as straightforward as I thought. Object.prototype.hasOwnProperty() From a Javascript interview point of view, I would think you just need to fully understand what obj.hasOwnProperty() does at the Javascript level
