Epsilon JavaScript

"Epsilon JavaScript" is a programming language that is an extension of the popular JavaScript language. It was created to provide a more concise, readable and efficient way of writing code. Epsilon JS provides several features that make it unique, including a simplified syntax, operator overloading, custom types, and more.

Features

Simplified Syntax

Epsilon JS has a simplified syntax that makes it easier to read and write code. For example, the following code in JavaScript:

var result = 0;
for (var i = 0; i < 10; i++) {
  result += i;
}
console.log(result);

Can be simplified in Epsilon JS as follows:

let result = 0;
for (let i from 0 to 10) {
  result += i;
}
log(result);

As you can see, the let keyword is used to declare variables and the from and to keywords are used to define a range for the for loop.

Operator Overloading

Epsilon JS allows for operator overloading, which means that operators can be redefined for user-defined types. This allows for more natural and intuitive syntax when working with objects.

For example, suppose we have a Vector class that represents a 2D vector. We can redefine the + operator to allow for adding two vectors together:

class Vector {
  constructor(x, y) {
    this.x = x;
    this.y = y;
  }

  add(other) {
    return new Vector(this.x + other.x, this.y + other.y);
  }

  // Define the + operator for the Vector class
  '+' (other) {
    return this.add(other);
  }
}

let v1 = new Vector(1, 2);
let v2 = new Vector(3, 4);
let result = v1 + v2; // This now works!

Custom Types

Epsilon JS allows for the creation of custom types which can have their own methods and properties. This allows for more expressive and modular code.

For example, we can define a Person class with a greet method:

class Person {
  constructor(name) {
    this.name = name;
  }

  greet() {
    return `Hello, my name is ${this.name}.`;
  }
}

let p = new Person('John');
console.log(p.greet()); // Output: "Hello, my name is John."

Plenty of Built-in Methods & Functions

Epsilon JS has a rich set of built-in methods and functions which can simplify common tasks. For example, the reduce function can be used to compute the sum of an array:

let arr = [1, 2, 3, 4, 5];
let sum = arr.reduce((acc, curr) => acc + curr, 0);
console.log(sum); // Output: 15

Conclusion

Epsilon JavaScript is a powerful and expressive language that provides several unique features. Its simplified syntax, operator overloading, custom types, and rich set of built-in methods and functions make it a compelling choice for many applications.
