 Best Practice for Code Reviewing JavaScript 

Code review is an important step in the software development process that helps ensure code quality, maintainability, and consistency. Here are some best practices for code review of JavaScript code:

1. Know the code standards: Familiarize yourself with the project's coding standards, naming conventions, and best practices before starting a code review. This will help you identify areas where the code deviates from established standards and make suggestions for improvements.

2. Focus on maintainability: Code review should focus on code maintainability, readability, and scalability. Look for easy-to-understand and maintain code, and suggest changes where necessary.

3. Check for best practices and conventions: Ensure that the code follows best practices and conventions, such as naming conventions, coding style, and indentation.

4. Verify that the code is performant: Check that the code is performant and does not contain any performance bottlenecks. This may include checking for expensive operations, memory leaks, and efficient use of data structures.

5. Check for compatibility with the target environment: Ensure that the code is compatible with the target environment, such as the browser or runtime.

6. Verify error handling: Check that the code handles errors correctly and that it has proper exception handling.

7. Review comments: Check that comments in the code are clear, concise, and helpful. Ensure that they provide context and explain the reasoning behind the code.

8. Consider automated tools: Automated tools can be used to help with code reviews, such as liners, code formatters, and code analysis tools. Use these tools to identify potential issues and help streamline the code review process.

9. Collaborate with the author: Code review should be a collaborative process between the author and the reviewer. Encourage open communication and discussion, and work together to identify and resolve any issues.


Final Thoughts 

Code review is an important part of software development and helps ensure that JavaScript code is of high quality, maintainable, and consistent with established standards and best practices. By following these best practices, you can make the most of your code review process and help ensure the success of your projects.

A Complete Guide to Using GUIDs in C# with Code Examples

  Overview In this post, we are looking at GUIDs (Globally Unique Identifiers), which are widely used in C# for generating unique identifiers for objects, entities, and resources in a system. In this post, we'll explore the basics of GUIDs in C#, their advantages, and how to convert strings to GUIDs. In this post, we have used Guid Generator to create the GUID from the following URL Address https://guidgenerator.com/ What is GUID GUID (Globally Unique Identifier) in C# is a 128-bit value that is used to identify objects, entities, or resources in a unique manner across different systems and applications. It is also known as UUID (Universally Unique Identifier) in some other programming languages.   GUIDs are generated using a combination of unique factors such as the MAC address of the network adapter, the current time and date, and a random number. The resulting GUID is a string of 32 hexadecimal digits separated by hyphens, such as "b86f2096-237a-4059-8329-1bbcea72769b...

Primitives Data Types and None-Primitives Data Types in C# with Code Examples

  Overview I wrote this post to provide an explanation of primitive and non-primitive data types in C#. C# is a strongly typed programming language, where each variable and expression must have a specific data type. C# data types are categorized into two primary groups: primitive data types and non-primitive data types. Primitive data types are the simplest data types available in programming languages. They are typically pre-defined data types and can represent a single value, such as a boolean value, character, or integer. Examples of primitive data types include int, char, float, double, and boolean, which are common in programming languages like C++, C, and Java. Non-primitive data types are also referred to as composite data types or reference data types. They are constructed from primitive data types and are more complex than primitive data types. Non-primitive data types can hold multiple values and allow for the creation of more intricate data structures like tables, li...

How to use Enum Data Values with .Net 6.0 Framework and Entity Framework Core 6

How to use Enum Data Values with .Net 6.0 Framework and Entity Framework Core 6 Overview An Enum (Enumeration) is a group of constants that are read-only value types. By default, the first value of the Enum variable is 0 i.e. Here we will create an Enum of Priorities type with read-only values of Highest, Normal and Low. We will set the read-only values using an integer assigning a number next to the value. By default, the integer value will start with 0. Here we will be assigning the integer value next to the Enum value such as in the below example and we will use a comma (,) to separate the item in the list of Enum(Enumeration).  We create Enum by using the Enum keyword and then using class, interface, and abstract. The reason we use an Enum is to ensure we improve our application performance and improve application readability, and maintainability, and reduces the complexity of the application hence why if you take a look at the example below of Status (NotStarted, Started, Comp...
