Static vs Dynamic Typing Toni Schumacher - uni-l?kde

Advantages of Dynamic Typing I Better for prototyping systems with changing or unknown requirements I Allows programs to generate types and functionality based on run-time

Why static type checking is more efficient than dynamic type checking?

Static checking / dynamic checking are two points on a continuum Silly example: Suppose we just want to prevent evaluating 3 / 0 –Keystroke time: disallow it in the editor –Compile time: disallow it if seen in code –Link time: disallow it if seen in code that may be called to evaluate main

CSE341: Programming Languages Lecture 18 Static vs Dynamic

• Common way to define a PL’s static checking is via a type system –Approachis to give each variable expression etc a type –Purposesinclude preventing misuse of primitives (e g 4/"hi") enforcing abstraction and avoiding dynamic checking •Dynamic means at run-time • Dynamically-typed languages do (almost) no static checking

CSE341: Programming Languages Lecture 18 Static vs Dynamic

Static checking • Static checking is anything done to reject a program after it (successfully) parses but before it runs • What static checking is performed is part of the PL definition –A “helpful tool” could do more • Most common way to define a PL’s static checking is via a type system

Static vs dynamic typing - University of Washington

• Most common way to define a P L’s static checking is via a type system – Approach is to give each variable expression etc a type – Purposes include preventing misuse of primitives (e g 4/"hi") and avoiding dynamic checking (dynamic means at run-time) • Dynamically typed PLs (Racket Ru by) do much less static checking

Is static type checking more efficient than dynamic type checking?

Static type checking is considered by some to be more efficient than dynamic type checking because, dynamic type checking may cause a program to fail at run-time due to type errors. In some programming languages, it is possible to anticipate and recover from these failures – either by error handling or poor type safety.

What are the advantages of a statically type-checked language?

If the type system can ensure that the value of each expression has a type compatible with the type of the expression, then type checking of most operations can be moved to compile time. There are many advantages to having a statically type-checked language.

Is static typing better than dynamic typing?

Yes, statically typed languages provided more optimized code but dynamically typed languages do this trade-off in order to achieve more powerful language features. For example- meta-programming and it is much easier to work in with dynamically typed languages. Thanks. Is static or dynamic typing better?

Are dynamic programming languages better than static programming languages?

Dynamic programming languages are generally more concise compared to static programming languages which do not use type inference. If this truly increases the Since the dawn of programming languages people have been arguing about typing and what kind is best.
