Data query and manipulation are experiencing a historic rise in popularity as modern companies become more reliant on data for day-to-day tasks. Businesses are looking for candidates and technologies that can efficiently generate results despite high volumes of complex data.
GraphQL (Graph Query Language) is the answer many companies are looking for. GraphQL offers tools for complex queries and a less-is-more approach to fetch calls, and it is projected to soon overshadow the REST API format as the query language of tomorrow’s job market.
Today, we’ll explore the key pieces of GraphQL and show you how to implement each in your own schemas. …
As part of this partnership, GitHub’s Nurturing Campaign offered engineering candidates who make it past a recruitment phone screen a 4-month gift subscription to Educative. GitHub has even extended the offer to candidates who do not receive an offer.
This gesture increases the pool of qualified, diverse candidates for the long haul by building empowered relationships with developer candidates, whether or not they move forward with GitHub.
In doing so, GitHub has made it possible for developers of all levels to pursue a career they love with ease. …
Software processes are the activities for designing, implementing, and testing a software system. The software development process is complicated and involves a lot more than technical knowledge.
That’s where software process models come in handy. A software process model is an abstract representation of the development process.
In this article, we will introduce you to the top seven software process models and discuss when to use them.
We will learn the following:
A software process model is an abstraction of the software development process. The models specify the stages and order of a process. So, think of this as a representation of the order of activities of the process and the sequence in which they are performed. …
With the release of React 16.8 in 2019, React Hooks have finally become available to use in our production applications. Hooks allow React developers to make functional components stateful and avoid Class Components.
UseEffect is one of the most popular Hooks allowing you to create conditional changes that reference the program state within a functional component.
Today, we’ll take a deeper look into one of the big 3 built-in React Hooks,
By the end, you’ll know how and when to implement this Hook to create reactive programs and understand why it’s so commonly used by React developers.
Here’s what we’ll cover…
In our last article on system design, we looked at the top 10 questions, including how to design a ride-sharing service like Uber or Lyft. Today, we take a deeper dive into system design questions and discuss how to design Uber’s backend.
This is a common question, one that you may encounter in any system design interview, especially if you’re interviewing for Uber. This question asks you to create a ride-sharing service to match users with drivers. Users input a destination and send their current location. Nearby drivers should be notified of new users within seconds.
Today, we will break down this question step-by-step. Let’s design a ride-sharing service like Uber! …
The mobile app market is quickly becoming one of the best platforms to reach modern customers. A common problem faced by front-end developers is creating user interfaces (UI) that look and work well on all platforms: Android, iOS, or even as a web app. Ionic UI software development kit is a common solution for this problem and allows front-end developers to make cross-platform apps with just a single codebase.
Today, we’ll get you started with Ionic, show you how it fits with other web technologies, and help you create your first Ionic app.
Let’s get started!
Getting a job rejection is discouraging. Today, we will walk you through six reasons why you might not be landing your dream job to help you tweak your application strategy.
If you’re on the tech job hunt, you know that it can be quite a challenge with many highs and lows. Rejection or being passed over for a coveted position can be discouraging hard to process.
Even now, with tech jobs on the rise, the struggle still remains, and many applicants report that landing their dream job has never been harder.
When facing rejection, we have two responses: give up from the devastation or keep trying and move past the rejection. It’s crucial to keep trying, especially in this climate. …

Python has many features for implementing functional programming concepts. When writing functional-style programs, you often need small functions that combine elements. Python has a built-in way to do this using lambda functions.
In computer programming, an anonymous function (such as a lambda expression) is a function not bound to an identifier. Lambda functions are an important part of functional programming that allow you to write throw-away functions without needing to name them.
In this Python tutorial, we will introduce you to lambda functions in Python and show you how to implement them in your own code. …

Sorting in programming involves placing elements in a list or an array in a certain order. Efficient sorting is important for optimizing other algorithms that require input data to be in sorted lists.
While you may not be required to implement a sorting algorithm in your day-to-day as a software developer, it’s important to know how some of these algorithms work internally. These are common for coding interviews and make you a more efficient developer.
In today’s article, we will explore two of the most popular sorting algorithms, merge sort and quicksort. …
