Javascript changing a global var from inside a function and then reading the new value from outside the function

Question

please dont close this as its not the same as an undefined var that you think this is the same question as its not.

Trying to change a global var from inside an async function then read it from outside the function, I will pop example on oh and i'm new to javascript, now if I read the value from inside the function its fine but not from outside. EDIT forgot to say its webaccess the var I'm wanting to use.

var webaccess = (0);
async function run() {
var result = (0);
  
  result = await contract.methods.name().call()
  console.log(`Token name: ${result}`)

  result = await contract.methods.balanceOf(account1).call()
  console.log(`Balance of account #1: ${result}`)

   if (result >= "10000000000000000000" && result < "12000000000000000000"){
   webaccess = (1);
   }
   if (result >= "12000000000000000000" && result < "14000000000000000000"){
   webaccess = (2);
   }
   if (result >= "14000000000000000000" && result < "16000000000000000000"){
   webaccess = (3);
   }
   if (result >= "16000000000000000000" && result < "18000000000000000000"){
   webaccess = (4);
   }
   if (result >= "18000000000000000000" && result < "20000000000000000000"){
   webaccess = (5);
   }
}
   
   run()

    if (webaccess == (1)){
      console.log(`webaccess pass = ${webaccess}`);
    }
    if (webaccess == (2)){
      console.log(`webaccess pass = ${webaccess}`);
    }
    if (webaccess == (3)){
      console.log(`webaccess pass = ${webaccess}`);
    }
    if (webaccess == (4)){
      console.log(`webaccess pass = ${webaccess}`);
    }
    if (webaccess == (5)){
      console.log(`webaccess pass = ${webaccess}`);
    }
