Which in some instances may appear to be an inconvenience as comments are an additional layer of notations, are essential for clear communication. Many a time, developers may believe that their reasoning is perfectly reasonable, but with time this information is disjointed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"the-impact\"><\/span><strong>The Impact<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Other people (including the developer, who probably wrote it) may have no idea what it does later on if there are no comments. That is why debugging becomes time consuming when some other team members are working on modifying features or even when introducing new talents into the presc ribed team.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-to-avoid-it\"><\/span><strong>How to Avoid It<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>Write Descriptive Comments:<\/strong> Always make an attempt to justify why you\u2019ve done what you\u2019ve done. Then, comment lines can be used to explain the what\u2019s and why\u2019s of a certain logic or the use of a function.<\/p>\n\n\n\n<p><strong>Utilize Docstrings: <\/strong>In languages where they are accepted use docstrings to do with documentation of classes and functions. This is especially useful in more elaborate projects due to its ability in bringing concepts or ideas into existence in the most effective way.<\/p>\n\n\n\n<p>Update Comments: Make sure comments updated every time the related code changes.

However, ignoring errors is a common coding mistakes. If an Error is not handled, a program can crash, data can be lost, or low-level system security breaches can occur.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"the-impact-2\"><\/span><strong>The Impact<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If they occur, the end user is left to fend for him or herself and this can create a lot of frustration. At its worse, it could compromise the security of your application and make it insecure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-to-avoid-it-2\"><\/span><strong>How to Avoid It<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>Implement Try-Catch Blocks: <\/strong>Try\/catch (or similar statements) must be used for handling errors gracefully. This lets your program to comeback or offer friendly error messages that can be easily understandable by users.<\/p>\n\n\n\n<p><strong>Validate Input:<\/strong> However, it is important to perform validation on the user inputs as a way of avoiding some unexpected outputs. Make sure that data is in required formats before going in to process it.<\/p>\n\n\n\n<p><strong>Log Errors: <\/strong>Use logging to print errors so they are traceable afterward. When attempting to troubleshoot, this can be helpful. one\u2019s code or finding which areas of the code need to be optimized.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3-hardcoding-values\"><\/span><strong>3.

Neglecting Code Reviews<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Some teams may decide that their members need not conduct a code review since they can identify all the problems themselves. These common coding mistakes can fail to identify areas that can be enhanced in future practice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"the-impact-9\"><\/span><strong>The Impact<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>While failing to perform reviews, developers lose important comments that can help the product get better. As a result, new bugs that went unnoticed, and ill-advised coding practices are made and coded into the system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-to-avoid-it-9\"><\/span><strong>How to Avoid It<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>Implement a Review Process:<\/strong> It is necessary to develop a culture of code review where different people will look at each other\u2019s code. This helps in increasing inter team communication and knowledge can be easily transferred between the different teams.<\/p>\n\n\n\n<p><strong>Use Pull Requests: <\/strong>Use pull requests in version control systems as it helps in enhancement discussion that happens before merge.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"10-ignoring-documentation\"><\/span><strong>10. Ignoring Documentation<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Most people have a perception that documentation is boring and as a result, they either do not complete it in its required format, or rush through the process. Most developers forget the usefulness of documentation and just sit and write codes all day.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"the-impact-10\"><\/span><strong>The Impact<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If an application is built without a well-documented structure, it becomes difficult for developers who join after the project initiation or users who have ideas on how an application should be used. This can actually slow development and limit production as a whole.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-to-avoid-it-10\"><\/span><strong>How to Avoid It<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>Document as You Go:<\/strong> You should write comments for your programs as you write the programs. What are functions, classes and how does a project setting look like?<\/p>\n\n\n\n<p><strong>Create User Guides: <\/strong>Ensure that the users are offered guides such as the user manuals and README files to enable them to use the software properly.

While writing code, they may produce efficient and well performing code without necessarily being able to optimize for efficiency of code.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"the-impact-11\"><\/span><strong>The Impact<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Often when code is written inefficiently, this often results in slow moving applications, high usage of resources and poor experience for the user, more so as the user base increases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-to-avoid-it-11\"><\/span><strong>How to Avoid It<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>Profile Your Code:<\/strong> By profiling, you\u2019ll get an idea of how your code runs and where you may have problems.<\/p>\n\n\n\n<p><strong>Optimize Early:<\/strong> Although everybody understands that one should write code to be functional at first, think about performance.
