Template Literals in ES6
Tags: webdev, javascript, angular, react
Published: 2021-03-31 15:41:10

**Uses/ Benefits**

1) Template literals are used to concatenate strings.
2) Placeholders/variables can be easily interpolated with template literals.
3) Makes code more readable and Clean

**How to write**

4) Strings or placeholders needs to be wrapped inside backtick
5) variables needs to wrapped like ${variable}


**Usecases**

1) Display  : The sum of 10 and 15 is 25.

```
let a = 10;
let b = 15;

"The sum of "+a+" and "+b+" is "+(a+b) +"." // ES5
`The sum of ${a} and ${b} is ${a+b}` // ES6
```


2) Display :
I am a Developer.
I love to code.



```
"I am a Developer.\nI love to code." // ES5
`I am a Developer. 
 I love to code.` // ES6 no need to use \n for new line. It will keep format same as written
```


3) Display : Let's code together

```
"Let's code together"  // ES5
'Let\'s code together' // ES5
`Let\'s code together` // ES6
```

Git and Collaboration
Tags: devjournal, github, collaboration, womenintech
Published: 2021-03-31 15:39:04

I've been using Git for a few years now, but most of the time I was working alone on small projects, what meant I only had to remember some basic commands and hardly ever had conflicts (just the few times I had to work on something with any of my colleagues).

Let alone PR. I had hear about them of course, specially when I started to look into resuming my career as a developer, but never had to create one before.

I can say that I learnt more about git and GitHub in this couple of weeks in the codeCollab program than in my previous years as a developer. 

We use GitHub to create the issues that need to be working on, assigning and tagging them appropriately and to communicate between us about our problems and concerns (if any) with them.

Then, after working on the feature on a separate branch, we create a PR that has to be reviewed and approved at least by 3 people of the team (we are 4 plus the senior engineers, which means we all get to review someone else's work). Once it is approved it gets merged, and if there is any conflict we solve it. 

To review an open PR, we pull the code to our local, ran it and test everything is working properly, flag any error or problems that arise and if none, approve it (and of course congratulate the person who did the job, it costs nothing to be nice and acknowledge the effort :wink:)

It can all seem pretty simple, even for me as I'm writing this now after two weeks doing it, but the first time you face it it can be daunting! I also downloaded a Git GUI, but I prefer to don't use it much and type the commands on the CLI to learn it better and get more confident with it now that I can.

And on top of the tools, I think this second and third week at codeCollab has been very good on communication. We still need to keep improving, but I think the initial shyness is slowly vanishing and we are speaking more among us, doing more meetings, overcoming blockers together and moving forward quicklier as a team. 

**Collaboration, communication and team working skills** are something that also need to be learnt and practised, besides coding, specially when working with remote teams in different timezones, something that looks like is in increasing demand nowadays. And I have the chance to learn, practise and improve them everyday. Thanks again Arit and Our Time for Tech for giving me the opportunity :pray:!

5 Reasons Why People Are Afraid To Code
Tags: codenewbie, codepen, programming, devlive
Published: 2021-03-31 15:35:45


The passion to learn new things is one of the major reasons why developers still code through the years. Let's take a look at the challenge faced by beginners who aspire to start a career on this path. 

##1. People Think it's Too Difficult 

Programming is difficult and can become frustrating if íts not understood. Learning the fundamentals of a programming language will make it easy and fun. In this case, you will gain more knowledge and experience as you practice consistently. 


##2. They Presume That They’ll Fail

Mindset is everything. If you think you are a loser so you are, vice versa. Your attitude towards a thing determines the outcome. Wrong motivations can not yield productivity.  Presuming that you’ll fail affects your mindset and soon enough you’ll start to have negative thoughts.

Those who fail are those who never start. 


##3. Beginners Think it’s Too Late to Learn

 Coding is a continuous journey it has no end. 
 The truth is programming is a never-ending skill that you need to develop. You don’t stop learning, pretty much like any profession. Age isn't a barrier to success. I have read stories of famous entrepreneurs who founded their companies at their old age. Age shouldn't stop you from achieving that goal you desire. 


##4. They Think They Aren't Meant to Code 

No man is an island of knowledge. Just because your program was unable to run at the first attempt doesn't define your journey into the future. Stop comparing yourself to others there is no superman anywhere. Keep trying and never be disappointed when you fail. 

##5. They Think it’s Expensive

Some people tell me how interested they love to learn to code but can't afford the cost. You see it's not about the cost it's about your actions. There are so many free resources online for beginners to start learning with. In my case, I took advantage of YouTube, and free e-books related to what I was learning at that moment. This same approach still works for beginners.
Simple Task Manager: trying Tailwindcss for the 1st time

Published: 2021-03-31 15:31:00

Bootstrapped with CRA and using Tailwindcss. I built a simple Task manager, it's incomplete and may have some bugs. I didn't have the intention to finish it at all but to try for the first time Tailwindcss.

I have to say, I really love working with that so called "Utility CSS Framework". In fact, I built the UI pretty fast.

Features (so far)
Register User
Login User
Tasks CRUD
Assign task to a registered user
Mark tasks as done
Add comments to any task
Edit/delete comments to any task (owner only)
Like comments
List Team members

Repo
https://github.com/AlexSegen/taskerapp.frontend

Demo
https://mytasker.netlify.app/

Notes
This "project" is using Context Api and it's only hooks based components.

Backend
This is using a simple ExpressJS backend built by me called Ninja (WIP).

How to test React Redux application with Jest

In this tutorial, we're gonna look at step by step to test React Redux application with Jest. This will apply on the <a href="https://grokonez.com/frontend/get-param-from-url-edit-item-form-react-redux-example">application</a> that we have built before. 

<!--more-->
<h2>Configure Jest and Babel for testing</h2>
- Install <code>jest-cli</code> and <code>babel-jest</code>:
<pre><code class="language-javascript">
yarn add jest-cli babel-jest
</code></pre>

- Open <strong>package.json</strong>, add <code>scripts</code>:
<pre><code class="language-javascript">
{
  ...,
  "scripts": {
    ...,
    "test": "jest"
  },
  "dependencies": {
    "jest-cli": "22.4.3",
    "babel-jest": "22.4.3"
  }
}</code></pre>
It helps us to run testing with cmd: <code>yarn test</code>.
For watching: <code>yarn test --watchAll</code>

- Open <strong>.babelrc</strong>, add <code>"env"</code>:
<pre><code class="language-javascript">
{
    "presets": ...,
    "env": {
        "test": {
            "presets": [
                "env",
                "react"
            ]
        }
    },
    "plugins": ...
}</code></pre>

- Run cmd: <code>yarn install</code>.

Now, we can run test inside <strong>filename.test.js</strong> file.
In this tutorial, we will use Jest <code>test()</code>, <code>expect()</code>, <code>.toBe()</code> and <code>.toEqual()</code> methods.

The Internet Initiatives Development Fund (IIDF) is the largest Russian venture capital fund. It assists digital and technology startups, at the idea and MVP stages, by providing investments for rapid growth. At first, IIDF’s own team developed the product as an internal service. After testing the hypotheses, they decided to turn it into a full-fledged recruitment app. To do this, they needed a team with experience that could build HRM software through hypothesis-driven development.

They turned to Evrone for help creating a platform for finding a startup co-founder or team members. In 3 months, we developed a complete web application and also tested customer scripts to make sure that all functions worked as expected for hypothesis testing.

Firebase Database CRUD Operations in React Webpack

Firebase Realtime Database is a cloud-hosted database that helps us to store and sync data with NoSQL cloud database in realtime to every connected client. In this tutorial, we’re gonna integrate Firebase into React Webpack, then we will look at way to make CRUD operations with Firebase Realtime Database.

<h2>Firebase Realtime Database</h2>
<h3>How data is structured</h3>
All Firebase Realtime Database data is stored as JSON objects without tables or records. When adding data, it becomes a node in JSON structure. For each node, we can:
– provide our own key (IDs/semantic names) and use <code>set()</code> method, or
– let it do automatically using <code>push()</code> method.
