Why is code reusability important in programming?

Code reusability is vital in programming primarily because it allows for faster development and reduces redundancy. When programmers can reuse existing code, they save time by not having to write new code from scratch for every new project or module. This efficiency fosters quicker delivery of software products, as developers can focus their efforts on unique features or improvements rather than rewriting well-established functionality.

Additionally, reusing code minimizes redundancy, reducing the chances of introducing errors, as the reused code is typically already tested and validated. This leads to more reliable software since components have been previously vetted. In essence, embracing code reusability streamlines the development process, allows teams to allocate resources more effectively, and fosters innovation by giving developers the bandwidth to tackle more complex problems rather than getting bogged down in repetitive coding tasks.
