| The most prominent difference of JavaScript and any strictly typed language is that, in TypeScript/JavaScript, a variable can reference a value of any type. This implies that a JavaScript VM has to conduct additional book-keeping of a value's type in addition to its value and that it has to perform additional checks whenever a variable is accessed. Modern JavaScript VMs shortcut the overhead introduced by this and similar dynamic features by generating case-specific code based on statistical information collected just in time, effectively reducing the amount of checks to perform implicitly and thus speeding up execution significantly. Similarily, developers shortcut the overhead of remembering each variable's type by using TypeScript. The combination of both also makes a good match because it potentially aids the JIT compiler. | ||

| Nonetheless, TypeScript isn't a *strictly* typed language after all because it allows specific constructs to resort to JavaScript's dynamic features. For example, TypeScript allows annotating function parameters as omittable (i.e. `someParameter?: number`), effectively resulting in a union type `number | undefined` at runtime, just like it also allows declaring union types explicitly. Conceptionally, these constructs are incompatible with a strict, AOT-compiled type system unless relatively expensive workarounds are introduced. Hence... | ||
