The Difference Between Regular Functions and Arrow Functions in JavaScript

Other then the syntactical differences. The main difference is the way the this keyword behaves? In an arrow function, the this keyword remains the same throughout the life-cycle of the function and is always bound to the value of this in the closest non-arrow parent function. Arrow functions can never be constructor functions so they can never be invoked with the new keyword. And they can never have duplicate named parameters like a regular function not using strict mode.

Here are a few code examples to show you some of the differences
this.name = "Bob";

const person = {
name: “Jon”,

<span style="color: #008000">// Regular function</span>
func1: <span style="color: #0000ff">function</span> () {
    console.log(<span style="color: #0000ff">this</span>);
},

<span style="color: #008000">// Arrow function</span>
func2: () =&gt; {
    console.log(<span style="color: #0000ff">this</span>);
}

}

person.func1(); // Call the Regular function
// Output: {name:“Jon”, func1:[Function: func1], func2:[Function: func2]}

person.func2(); // Call the Arrow function
// Output: {name:“Bob”}

The new keyword with an arrow function
const person = (name) => console.log("Your name is " + name);
const bob = new person("Bob");
// Uncaught TypeError: person is not a constructor

Parenthesis Balancing using Monoids in TypeScript

The Parenthesis Balancing problem is a classic problem that says :

Given an expression string exp, write a program to examine whether the pairs and the orders of “(“, “)” are correct in exp.

so this (()()()())is balanced but this one ())) is not

in this article we are going to solve this in a functional manner using Typescript and the monoids from the previous article.

Monoids in TypeScript

“Alternatively, the fundamental notion of category theory is that of a Monoid”

medium.com

we are going to define a simple balance type that will hold the number of the left end right values.

this amazingly forms a monoid. Since we can concatenate two Balance objects and get a new balance.

Chatbot Architecture: Types, Function & User Interaction

One of the primary needs of today’s businesses is instant and open communication. Many companies have realized the importance of advanced technologies like Artificial Intelligence and Chatbots for robust communication with their customers.

So much so, that in the near future advanced Chatbots are set to replace humans. This is possible because of a Chatbot’s ability to “learn” by discovering patterns in data.
