All languages are designed to translate human-readable code into machine instructions.

graph LR; id1[Source Code] --> id2[Compile Time] id2 --> id3["Executable File"] id3 --> id4["Run Time"]

Type checking occurs at compile time.

A variable doesn’t need to be defined before it is used.

Static Languages: Java, C++

// C++ Example
int UniqueName;
uniqueName = 5;

Type checking occurs at runtime.

Variables must be defined before they are used.

Dynamic Languages: Javascript, PHP

// PHP Example
$txt = "Hello world!";

Variables are bound to a data type.

// C++ Example
int UniqueName;
uniqueName = "String"; // Throws error, variable can only have integers

Variables are not bound to a data type.

# GDScript Example
var item = 5;
item = "Hello" # Data type can be changed for variable
