Typescript how to say two value will be same type but they could be anything-CodePudding

My question is for example there is a interface like this

interface Example {
value: any;
otherValueToCompare: any;
}

They could be anything, but they should be same type. If someone tries to send a string for value, otherValueToCompare's type should be string too.

How can it achieved?

CodePudding user response：

You can use generic types to achieve this:

type Example<T> = {
    value: T;
    otherValueToCompare: T;
}

const s: Example<string> = {
    value: 'x',
    otherValueToCompare: 'y'
}

const p: Example<number> = {
    value: 1,
    otherValueToCompare: 2
}
