Javascript frameworks

This page covers JavaScript frameworks and libraries. JavaScript frameworks are among the most widely used tools for web and mobile development. These frameworks are primarily divided into back-end and front-end categories, with a few frameworks, such as Next.js, being full-stack.

Since all these JavaScript frameworks use JavaScript as their core programming language, we strongly recommend that you also include a JavaScript exam in your job offer. This will help you assess whether the candidate has a solid understanding of JavaScript.

As with all our exams, the website will monitor the user by recording both their webcam and screen. These videos will be merged into one, allowing the employer to observe the candidate throughout the entire exam. This process helps prevent cheating through chatbots, friends, or unauthorized resources. At the end of the exam, our AI will analyze the candidate's performance and compile a PDF report with relevant statistics to provide insights into the candidate's abilities. Additionally, a global PDF report will compare the results of all your candidates, create a ranking, and highlight which candidate shows the most potential for your job offer.

There are several ways to send exams to a candidate or potential employee in this section:

1. Job Offer: You can attach any exam to your job offer. The candidate must pass the exam to be eligible to apply.
2. Email: You can send the exam link directly to a candidate’s email. Once they click on the link, they can take the exam, and you will receive both the video and the PDF report.
3. Direct Messaging: On the message page or within the WorkFrater chat box, you can send the exam directly to your candidate. By clicking on the exam link, the candidate can complete the exam, and you will receive both the video and the PDF report.

The link to all our exams is here . Most of the exams in this section consist of multiple-choice questions, where the user can select one correct answer from several options. Each question has a time limit, and users cannot skip a question and return to it later.

At the beginning of the exam, the website will ask users general questions about their knowledge of specific JavaScript frameworks. Questions will cover the compilers and plugins used, as well as work experiences and personal projects.

After this initial interview step, the real questions begin. For Level 1 JavaScript frameworks and libraries, the questions are generally divided as follows:

1. Setup and Command Lines: Framework installation, package management, command lines
2. Navigation and Workspace: File structure, framework specificities
3. Core Tools: Components, states, lifecycle
4. Routing and Data: Client-side navigation
5. Optimization: Performance optimisation, lazy loading, concurrency and threading
6. Security: Password management, XSS prevention, csrf prevention, SQL injection
7. Plugins and Extensions: Managing external and third-party tools
8. Database integration: Integration of a simple SQL-like database

To complete the test, all JavaScript framework exams have a final section with basic JavaScript questions to assess the candidate’s understanding of core JavaScript concepts. The topics covered include:

• Variables
• Conditions
• Loops
• Methods
• Classes

Although all the exams in the JavaScript frameworks section include questions on the JavaScript programming language, we encourage you once again to include a basic JavaScript assessment test in your job offer.
