A design pattern is a reusable solution to prevent programming problems that occur frequently.
Design patterns are optimized, reusable solutions for the programming problems we encounter many times. A design pattern is like an template that you can implement in your software. It’s is not language-specific and can be used in almost every programming language. Another great advantage is that reusing these patterns helps to prevent issues that cause major problems but also helps code readability for other programmers familiar with design patterns so they can understand and work with the code easily. Therefore, programmers familiar with some of the most common design patterns can contribute widely on projects with much more ease.
Every developer strives to write maintainable, readable, and reusable code. It’s like playing with Lego: there’s a handful of different pieces you get to snap together however you want. Sometimes you make something cool, but most of the time you make crap. However, the longer you play, the better you get.
Studying Design Patterns is much like learning “how to build applications in a good way”. By studying these patterns we mostly read advice from other programmers that have been programming and creating applications for decades. They have distilled their most common solutions into simple, understandable pieces of knowledge with memorable names. One could see it like an apprenticeship for the digital-age: the elders are giving their best advice. You can take it and be ahead of the game, or ignore it and repeat all of their mistakes.
