Union Types

Save

Union Types are a powerful feature of TypeScript that allow you to specify that a variable can have more than one type. This can be useful in a variety of situations, such as when you want to represent a value that can be either a string or a number, or when you want to represent an object that can have multiple different properties.

Why Learn Union Types?

There are several reasons why you might want to learn about Union Types. First, Union Types can help you to write more flexible and robust code. By allowing you to specify that a variable can have multiple types, you can avoid the need to check the type of a variable before using it. This can make your code more efficient and easier to read.

Second, Union Types can help you to improve the safety of your code. By specifying the types of values that a variable can have, you can help to prevent errors from occurring. For example, if you have a variable that is supposed to represent a number, you can use a Union Type to specify that the variable can only have values that are numbers. This can help to prevent errors from occurring if someone tries to assign a non-number value to the variable.
