Study Notes
Dynamic Type Binding in Programming Languages
- Assignment statement binds variable to type of value on right side
- Variable may also be bound to address and memory cell
- Variable's type can change during program execution
- Dynamically bound variable's type is temporary
- Dynamic binding provides more programming flexibility
- Before mid-1990s, most languages used static type binding
- Shift to dynamic type binding in languages like Python, Ruby, JavaScript, PHP
- Example of dynamic type binding in JavaScript
- Dynamic type binding introduced in C# 2010 using the "dynamic" reserved word
- Disadvantages of dynamic type binding: less reliable, cost
- Error detection in dynamic binding is diminished
- Cost of implementing dynamic attribute binding is considerable
