I have a button in my react app that i only want it to be pressed once

Question

I have implemented this onclick event in it and I want the functions inside the onclick event to run once

    <button className='btn2' onClick={() => {

OpenForm();

      if (IsLoggedIn === true){
        Like();
    }else if(IsLoggedIn === false){
    return;
    }
      }}>

What you need to do is keep track of that using state, let's say a hasClicked, the default state will be false and you changed that in the onClick handler you have up there, an example code snippet would be like:

import { useState } from 'react'

const MyComponent = () => {
    const [hasClicked, setHasClicked] = useState(false)
    ...

    const btnClickHandler = () => {
        ...
        setHasClicked(true)
        ...
    }

    return (
        <button disabled={hasClicked} onClick={btnClickHandler}>Click<button/>
    )
}

That way, the button will be disabled once the user clicks on it because disabled will now be pointing to a true hasClicked value.
