JTS Development Kit v2.0.0

What is JTS GO?

JTS GO is a programming language designed for absolute beginners. If you've never written code before, this is where you start.

• Python-like syntax — readable, indentation-based
• Object-Oriented Programming — classes, methods, inheritance
• Dynamic typing — no need to declare variable types
• Built-in ML/AI — tensors, matrices, activation functions
• Web Development — HTTP server support
• Simple toolchain — one command to run your code
• Compiled to bytecode — fast execution via a virtual machine

Quick Start

Install via npm

npm install -g @jaytechsolutions/jts-go

Then run any .jts file:

jts hello.jts

Update

jts --update

Hello, World!

print("Hello, World!")

Save as hello.jts and run:

jts hello.jts

Language Features

Variables

# Dynamic typing
name = "JTS GO"
version = 2.0
is_awesome = true
nothing = nil

# Type-annotated declarations
int age = 25
string greeting = "Hello"
float pi = 3.14
bool active = true
list numbers = [1, 2, 3]
var x = 42

print(name)

Object-Oriented Programming

# Define a class
class Animal
    func init(self, name)
        self.name = name
    end

    func speak(self)
        print(self.name + " makes a sound")
    end
end

# Create an instance
a = new Animal("Dog")
a.speak()           # Dog makes a sound
print(a.name)       # Dog

# Inheritance
class Dog extends Animal
    func bark(self)
        print(self.name + " barks!")
    end
end

d = new Dog("Rex")
d.speak()           # Rex makes a sound (inherited)
d.bark()            # Rex barks! (own method)

Functions

func greet(name)
    print("Hello, " + name + "!")
end

func add(a, b)
    return a + b
end

print(add(3, 4))   # 7

Lists

nums = [1, 2, 3, 4, 5]
print(nums[0])       # 1
append(nums, 6)
print(len(nums))     # 6

Control Flow

# If/Else
if score >= 90
    print("A")
else
    print("B")
end

# While loop
i = 0
while i < 5
    print(i)
    i = i + 1
end

# For loop
for i in 0 to 10
    print(i)
end

ML/AI Functions

# Tensors
t = tensor([1, 2, 3, 4, 5])
print(t)

# Matrices
m1 = matrix([[1, 2], [3, 4]])
m2 = matrix([[5, 6], [7, 8]])
result = matmul(m1, m2)
print(result)

# Activation functions
print(sigmoid(0))    # 0.5
print(relu(-5))      # 0
print(relu(5))       # 5

# Loss functions
print(mse([1, 2, 3], [1.1, 2.2, 3.1]))

Web Development

# Create and start an HTTP server
server = http_server(8080)
http_start(server)

Math Functions

print(sqrt(16))        # 4
print(math("sin", 3.14159))  # ~0
print(math("floor", 3.7))    # 3
print(math("abs", -42))      # 42

String Conversion

print(str(42))          # "42"
print(str(true))        # "true"
print(str(nil))         # "nil"
