Lumen
Lumen is a compiled, lightweight, and fast programming language.
It has familiar syntax that is great for beginners who want to learn C languages like C, C++, or C#,
and is great as an intermediate language between Python and C, as it teaches many C concepts while keeping the friendliness of Python.

Examples:
Goto Label Logic:
goto start;
print "This will be skipped!":
start:
print "Hello from start!";
Functions:
fun function(thing1, thing2) {
print "First data is", thing1;
print "Second data is", thing2;
};
function(data1, data2);
Conditional Logic:
if (condition) {
code;
};
while (condition) {
code;
};
Declaring Variables:
int integer 0;
str string "Hello!";
bool boolean False;
var anyData "This can be any type of data!";
static str staticVar "This variable cannot be changed.";
ary array[0,1,2];
dic dictionary{
"key":"content";
};
Example Program:
int number 0; // Can only be an integer
bool thing True; // Can only be a Boolean
str stringThing "This is a string!"; // Can only be a string
var dynamicVar "WOW!"; // Can be any data type
static var stuckThing "Hello"; // CANNOT be changed
ary arrayThing["Index 0","Index 1","Index 2"]; // Can only be an Array
dic dictThing{
"key1":"content1";
"key2":"content2";
}; // Can only be a Dictionary
// Single line comment
/*
Multi
Line
Comment
*/
fun program(condition, num) {
if (condition) {
print "Condtion is True!";
while (num != 100)
{
print "The number is ", num;
num++;
};
};
};
program(thing, number);
print dictThing["key1"]; // Will return "content1"
print arrayThing[1]; // Will return "Index 1"
