Application of strategy pattern in front-end development: making code more elegant

Today we are going to talk about a Design pattern that makes your front-end code more elegant — the strategy pattern. If you haven’t followed our official account yet, click on the “Follow” card above, and let’s have fun in the programming world together!

Strategy Pattern Overvie

Strategy Patterns, it sounds like we are fighting a battle and using different strategies to defeat the enemy. In fact, in the programming world, we are also “fighting” against various problems, and Strategy Patterns are one of our “weapons”. It can help us abstract some operations into a set of independent strategies, and then dynamically choose a strategy to perform actions at runtime.

But that’s not to say that we need to create a strategy for every problem. Instead, the strategy mode emphasizes choosing the most suitable strategy in different environments and needs. Just like in battle, we don’t blindly choose weapons, but choose the most appropriate strategy based on the characteristics of the enemy and the current environment. This is the charm of the strategy mode.

Strategy Patterns in Front-End Development

So, how do we use policy patterns in front-end development? There are many problems that can be solved by strategy patterns, such as optimizing if/else Code Block, handling different browser compatibility issues, or doing form validation.
