One of the biggest issues is that a developer may struggle to consider all the different types of errors that can occur in an application, let alone find a solution to mitigate them.<\/p>\n<p>Developers must then develop an error handling routine capable of reacting to errors when they occur. If this routine isn&#8217;t robust enough, then the end user application could crash.<\/p>\n<p>Finally, a developer must consider the computational footprint of implementing error handling. If the error handling process is too computationally intensive, then the performance of the end user application will suffer.<\/p>\n<h2><span id=\"error_handling_security_issues\">Error Handling Security Issues<\/span><\/h2>\n<p>There are also some significant security issues to consider. One of the most important is that shipping codes with flaws can provide vulnerabilities that a <a href=\"https:\/\/www.techopedia.com\/definition\/threat-actor\">threat actor<\/a> can exploit.\u00a0 For this reason, developers need to be mindful of improper error handling and strengthen their efforts with <a href=\"https:\/\/www.techopedia.com\/antivirus\/best-antivirus-software\">tools like antivirus software<\/a> to protect applications against attacks.<\/p>\n<p>But what is improper error handling exactly? It occurs when an error message is displayed to the end user, providing details that a hacker can weaponize to compromise the application&#8217;s data and other key systems.<\/p>\n<h2><span id=\"the_bottom_line\">The Bottom Line<\/span><\/h2>\n<p>Now you know the meaning of error handling, it&#8217;s worth underlining that it is a fundamental practice to ensure an application performs well. Without proactively managing errors, it&#8217;s going to be difficult to keep your application up and running and offer an experience that keeps users coming back for more.<\/p>\n<p>Taking small steps like proofreading your code can go a long way toward minimizing the chance of disruptions and crashes when your app is in operation.<\/p>\n<h2><span id=\"faqs\">FAQs<\/span><\/h2>\n<div class=\"man_faq_sec\" itemscope itemtype=\"https:\/\/schema.org\/FAQPage\"><\/time><section class=\"ms_faq ms_card \" ><div itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"><div class=\"accordionButton\"><h3 itemprop=\"name\">What is error handling in simple terms?<\/h3> <\/div>\n<div class=\"accordionContent\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\" style=\"display:none;\"><p itemprop=\"text\">Error handling is the process of identifying, managing, and mitigating errors in software applications.
