Union Types

Union Types in TypeScript allow you to specify multiple possible types for a single variable or parameter. A union type is written as a vertical bar | separated list of types.

For example, consider a function that takes either a string or a number as an argument:

function combine(input1: string | number, input2: string | number) {
    return input1 + input2;
}
