JavaScript is very strongly typed. Everything will have a type. And it will be enforced and checked during runtime. This will prevent buffer overflows and memory leaks. JavaScript is dynamically typed. This allows you to to do funny things like [1,2,3] + ",4" Because it's strongly typed, all values will be converted to a type. JavaScript does type checking during compilation, but it's not considered a static language, because it allows "duct typing" meaning you can add or remove properties and methods on objects during runtime.
