Part 5.1Types of programming languages

There are many different programming languages out there much like there are different spoken languages in the world. Modern programming languages are built on top of the older programming languages and have the benefit of becoming richer in syntax at the cost of performance (or taking longer to actually write) without making much difference to the outcome of the program. For instance, here are five implementations of the same program in different languages:

var x = 10;
var y = 20;
console.log(x * y);

$x = 10;
$y = 20;
echo $x * $y;

int x = 10;
int y = 20;
System.out.println(x * y);

$x = 10;
$y = 20;
print ($x * $y)

Dim x As Integer = 10
Dim y As Integer = 20
Console.Write(x * y)
