It provides you with real-time feedback and more documentation on function arguments, object shapes, and undefined variables. As the developer, it saves time on your side to not have to search for or update documentation manually.<\/p><h3 class=\"wp-block-heading\"><strong>2- Prevents Errors And Waste Time<\/strong><\/h3><p>TypeScript reduces the debugging process and guarantees precise object shapes. This stops developers from expecting that some required fields can be filled in by wingman or depending on out-of-date documentation.<\/p><h3 class=\"wp-block-heading\"><strong>3- Object-Oriented Programming (OOP)<\/strong><\/h3><ul class=\"wp-block-list\"><li><strong>Code Reuse:<\/strong> Through inheritance, one can reuse logic while maintaining clear hierarchy.<\/li>\n\n<li><strong>Flexibility:<\/strong> A single object can take multiple forms by the principle of polymorphism, thus reducing the duplication of code.<\/li>\n\n<li><strong>Encapsulation: <\/strong>The data is protected because it is kept private within classes.<\/li>\n\n<li><strong>Problem Solving:<\/strong> The creation of classes helps in breaking down complex tasks into small and manageable chunks.<\/li><\/ul><h3 class=\"wp-block-heading\">4- <strong>Static Typing<\/strong><\/h3><p>Static typing guarantees that the code is self-documenting and structured and finds flaws early.
