Waiting for dynamically loaded script

Question

In my page body, I need to insert this code as the result of an AJAX call:

    
Loading jQuery
    

        

Answer 1

const jsScript = document.createElement('script')
jsScript.src =
  'https://coolJavascript.js'

document.body.appendChild(jsScript)

jsScript.addEventListener('load', () => {
  doSomethingNow()
})

Will load after the script is dynamically added
