Uses of Software Design Patterns

There are two main uses of design patterns. First, design patterns create a common platform for developers with their terminology. For example, during a technical discussion, let's assume that a design decision is made to use a single instance of a component. All other developers, at least the ones that are aware of design patterns, will not need any further information considering the properties of the singleton pattern. Although this looks trivial, it is an enrichment of communication, with the best practices of technical expertise. Secondly, knowing and leveraging best practices in engineering makes it easier to advance rapidly. Let's imagine that you are designing a car – you should always start by inventing the best wheel possible first. This makes the process faster and eliminates the gains of learning from past
mistakes.
