Static vs Dynamic Type Checking. Java uses static type checking, where the type of a variable is checked at compile-time. The programmer must specify the type (integer, double, string, etc.) of any variable they create. JavaScript, like most scripting languages, uses dynamic typing, where type safety is verified at runtime. A type system reduces risk, is a communication tool, and enhances the architecture. As JavaScript code bases grow both in size and complexity, there is value in type checking. A good type system builds on top of JavaScript native types and does basic type checking. Consider adding type checking as part of a build to shorten the feedback loop.
