A Function in Typescript/Javascript that can only be called/executed once

index.ts

/*
  I wanted a function that would only work once where all subsequent calls would result in a noop
  
  I stumbled upon this Stackoverflow question: https://stackoverflow.com/questions/12713564/function-in-javascript-that-can-be-called-only-once
  However, I found some of the answers difficult to implement in Typescript but on the bright side.  I learnt a little about closures.
  I added my simple workaround here: https://stackoverflow.com/a/72992927/2719085 and below.

let printName = (name: string) => {
    console.log(name)
    printName = () => {}
}

printName('Sophia') // Sophia
printName('Nico')   // Nothing Happens
