Dynamic typing VS Static Typing

Feature	Dynamic	Static
Type Checking	At runtime	At compile time
Variable types	Determined when code runs	Declared before running
Flexibility	More flexible, less boilerplate	Stricter, but safer
Errors	May fail at runtime (type errors)	Type errors caught early (before running)
Performance	Usually slower	Usually faster
Scope	Better for fast, small personal projects	Better for big projects that needs lots of collaboration
Examples	Python, JavaScript	C++, ☕Java

Dynamic Typing

A language is dynamically typed if the type is associated with run-time values, and not named variables/fields/etc

• You don’t declare variable types explicitly.
• The type is inferred at runtime based on the assigned value.
• Convenience and readability - easier to understand
• The computer decides, so efficiency is low
• Better suited

Static Typing

A language is statically typed if the type of a variable is known at compile time.

• You explicitly declare variable types, or the compiler infers them at compile time.
• Detailedness, lots of safety devices
• Prevents mistakes
