seamlessly call any JS code. Swift: Bidirectional (Swift calls ObjC, ObjC calls Swift), ObjC-friendly object and lifetime models (ObjC ARC + modules designed for Swift), automatic bridging header generation generation, tool support to view ObjC as if written in Swift. Roslyn next-gen C# compiler: Strict compatibility requirements, adhered to rigorously via compat tests. Compatible with JavaScript Cooperates seamlessly call any JS code.

2002, 2005 JVM – Java Native Access (JNA) – 2007 Go – cgo – permit C in the .go source file – 2009 Swift – share a runtime and be like C – 2014There is no one approach. Make it suck less by recognizing Reference counted - C++ – std::shared_ptr - Python - Objective-C (manual or automatic – see ARC) - Swift - COM – AddRef()/Release() - Non-Reference counted - .NET - JVM - JavaScript Manual memory management
