"isolatedModules": true in tsconfig.json is not throwing errors for my typescipt file that doesn't have an import/export

I am watching the following vide: https://teamtreehouse.com/library/typescript-basics/going-through-the-typescript-configuration-file

Towards the end of the video, he talks about setting isolatedModules to true in tsconfig.json. The index.ts file has the following code: 

function logName(){
    const name: string = "Lucas";
    const msg: string = `Hello ${name}`;

    console.log(msg);
};

In his example, he gets an error saying index.ts cannot be compiled under '--isolatedModules

However, when I put the exact same code and tsconfig in my own local project, I don't get that error. Can someone explain why? Thank you!
