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.

Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.

Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

Your Reference Guide to Using TypeScript in React

One of the issues with JavaScript is its dynamically-typed nature, meaning that data and variable types are unknown until runtime. This can have many side effects. For example, it can cause confusion within your codebase due to the fact that a variable can be anything.

To solve this issue, Microsoft released TypeScript. Anders Hejlsberg, lead architect of TypeScript, said, “What if we could strengthen JavaScript with the things that are missing for large scale application development, like static typing, classes [and] modules…? That’s what TypeScript is about.”

TypeScript instantly became the most widely used static-typed version of JavaScript. It enabled JavaScript devs to statically type data and variables. Soon enough, it was introduced to React.js, enabling React devs to write their React app in TypeScript.

But this comes at a cost: TypeScript typings and syntaxes can be difficult to keep up with, especially when used with React.

React has many features, such as props, class components, function components, function params, components lifecycle hooks, and member properties. Because typing these within TypeScript isn’t easy, this article aims to serve as a quick reference and learning guide for both beginner and advanced React devs.

With it, you’ll be able to quickly look up best practices and generic TS types in React. Ready? Let’s get started.

TypeScript typings

TypeScript has a typings folder where it saves files with *.d.ts extension. These files include interfaces that infer what shape a value will take. This is what enables TypeScript to bring data-typing to JavaScript.

An interface describes what a value would look like:

type AppState {
    propOne: number;
    propTwo: string
}

AppState describes what the value of its data-type would look like. First, we infer it would be an object that holds properties propOne and propTwo, the former being of number type and the latter being a string type. Assigning a boolean type to propOne would cause TypeScript to throw TypeError.

When we include TypeScript in our React project, every React element has an interface that defines the shape it will take. Let’s start with function component.

Function component

Function components are normal functions that return JSX elements in React and are used to create views. Initially, they are stateless components, but with the arrival of React hooks, they can be made stateful and smart/

Defining a React function component takes the React.FunctionComponent shape:

function App: React.FunctionComponent<> {
    return (
        <>
            // ...
        </>
    )
}

We can also use the shorthand React.FC:

function App: React.FC<> {
    return (
        <>
            // ...
        </>
    )
}

React.FunctionComponent, or React.FC, describes explicitly the return type of the function component.

We can type the props definitions in the arrows <>.

type AppProps = {
    message: string;
    age: number;
};

AppProps is the interface the props passed to App will take, so we can write the App component below if it would receive props:

type AppProps {
    message: string;
    age: number;
}

function App: React.FC<AppProps>(props: AppProps) {
    return (
        <>
            // ...
        </>
    )
}

We can use ? to set optional values in the typing:

type AppProps {
    message: string;
    age?: number;
}

Now, the age property becomes optional. The App component can be rendered, omitting the age property in its props object.

We can omit the type declaration within the arrows <>.

function App<{message: string; age: number;}>({message: string; age: number;}: AppProps) {
    // ...
}

Inner functions in the functional component can be typed, like so:

function App<{message: string; age: number;}>({message: string; age: number;}: AppProps) {
    // ...

    function clickHandler (val: number) {
        // ...
    }

    return (
        <>
            <button onClick={() => clickHandler(45)}            
        </>
    )
}
