TypeScript, Microsoft’s JavaScript for big applications, reaches version 2.0 | Ars Technica: "TypeScript 2.0 brings a range of new features, but the biggest is control over these null values. With TypeScript 2.0, programmers can opt into a new behavior that by default prevents values from being null. With this option enabled, variables by default will be required to have a value and can't be set to null accidentally. This in turn allows the compiler to find other errors such as variables that are never initialized."
