How to annotate object as function argument?

Question

I am trying to invoke this function

const logPerson = (person: { name: string; age: number }) => {
    console.log('name:', person.name, 'age:', person.age);
}

I tried

let person = (_name:'Mike Pompeo', _age:'25')

But

logPerson(person)

returns

[LOG]: "name:",  undefined,  "age:",  undefined

How to fix this?

"I tried let person = (_name:'Mike Pompeo', _age:'25') but logPerson(person) returns [LOG]: "name:", undefined, "age:", undefined." All due respect, I find that hard to believe. let person = (_name:'Mike Pompeo', _age:'25') is a syntax error as of the first : (in JavaScript) or the ) (in TypeScript). — T.J. Crowder

person should be object. And also remove _ for the key name.

let person = {name:'Mike Pompeo', age:'25'}
