for others that will be in the same situation as I am, here is the solution.<\/p>\n

first step, I made the captcha<\/code> function to return a promise<\/p>\n

function captcha() {\n    return new Promise(function(resolve, reject) {\n      grecaptcha.ready(function() {\n        grecaptcha.execute(recaptcha_site_key, {action: 'run'}).then(function(token) {\n          resolve(token);\n        });\n      });\n    });\n}\n<\/code><\/pre>\n
second step,  async\/await for the variable to become available<\/p>\n
async function run() {\n  let g_recaptcha_response = await captcha();\n  document.forms['params'].elements['g_recaptcha_response'].value = g_recaptcha_response;\n  let data = input();\n  data = confirm(data);\n  if (data['error'] === true) {\n    return data;\n  }\n  let url = `${origin}\/app\/json`;\n  data = request(url, data);\n  \/\/ note: preparing for input \/ next request.\n  document.forms['params'].elements['token_id'].value = data['token_id'];\n  return data;\n}\n<\/code><\/pre>\n
third step, create an IIFE at the top-level<\/p>\n
(async function(){ let response = await run(); })();\n<\/code><\/pre>\n<\/p><\/div>\n
