Bug is a term used to describe problems or errors in the code and function of a website that cause it to not function properly. This problem can occur in various forms, such as website features not working, a damaged display or user interaction errors. A bug can cause software, websites or systems to not function properly and even crash.

Bugs also include technical errors that have security risks. If the software has security gaps due to bugs, hackers can insert malware, steal important user data and so on. The causes of this bug are very diverse and there are several types of bugs that often occur.

1. Performance Defects 

Performance Defects are a problem with websites, especially those related to response time, speed, stability and resource usage, so you have to check for the presence of these performance defects. This error can occur due to a bug in the performance and speed of the website you are accessing.

2. Functional Error 

Functional defects are errors that can occur in website features or functions so that they cannot function as they should. For example, forms cannot be filled out, buttons do not work, pages cannot be accessed properly and others.

3. Compatibility Error 

Compatibility errors are problems with the appearance of a website so that it does not function properly on a number of devices or browsers. One of the causes is a compatibility error. This bug can occur when the website is not compatible with a number of devices and browsers used by the user.

4. Usability Defects 

Usability is a problem related to user experience. This can happen because the website has a very complicated UI design so users have difficulty finding the information they need. An example that often occurs because of this is that the layout of the website page is unclear and buttons are difficult to identify.

5. Syntax Error

This bug can occur if there is an error in writing the code or syntax on the website. Syntax errors can cause the website to not function properly or even crash.

6. Security Error 

When compared to other bugs, security errors are the most dangerous because they relate to website security. This bug can explore security weaknesses in a website. In this way, security data errors can steal or damage the website.

7. Logic Error 

Logic errors are problems or bugs related to the logic or algorithms used on a website.

Based on this explanation, a bug is a term for an error that occurs on a website or application with various types that can occur. You have to be careful if bugs occur because they can damage the website.

Bugs do not occur suddenly, but there is a cause and below are several examples of causes of bugs that often occur:

1. Complicated Software

One of the causes of bugs is complex software, which increases the occurrence of bugs. A lot of code running in software at the same time will require proper coding. If a code error occurs, it can affect the working system of the software/

2. Bad Communication

The second cause of bugs is poor communication. Usually website or software development will be related to many parties, such as programmers, testers and clients. If the communication is not good, it will cause bugs.

For example, when a tester finds a bug in the software he created but doesn’t convey it to his team. Developers will make changes because they need new features on the website. Well, because bugs are not communicated to other teams, this can cause the feature to not work properly.

3. The deadline is tight

The third cause of bugs is related to damage to the software. This can cause tight deadlines, but the software is not yet perfect. The software being worked on will cause errors and an increase in bugs. For example, the bugs are so tight that there are features on the website that have not been tested properly.

4. No Code Change Log

Bugs can also occur because there is no code change log. Every code written produces output differently. If there are code changes, but they are not documented, it can cause logic bugs.

These are some of the causes of bugs because bug means the term if there is a problem with the software or website so it must be resolved immediately and properly.

Tips to avoid bugs that can be done are:

1. Build Communication Between Teams

The first tip you can do to avoid bugs is to build communication between teams. A team must be able to communicate well while running the application being created. Apart from that, division of tasks and high levels of trust can make work easier and minimize the occurrence of errors.

2. Run a Bug Bounty

A tip to avoid bugs is to run a bug bounty because if your entire team has run the program from start to finish it doesn’t mean the program created is free from bugs. That’s why, you need to make sure the program is ready to use by running the program using another device and registering as a user too.

3. Testing Program

The next tip to avoid bugs that must be done is to test the program first before launching. Before you send the program so that it can be used properly, you must test the program.

This test is carried out from the start of using the program to the end of use. Bugs can also occur in mobile apps so testing and debugging need to be done first.

4. Agile Methodology

The final tip is to run technique agile methodology, which is a technique that prioritizes continuous development. By using this technique, the changes made must be approved by the team first. You need to reduce the quantity of changes to the program and also reduce the bugs that can occur in the program.
