    var answer = firstFunction();   
    console.log(answer) 
}

function firstFunction() {
    //Do something;

You'll need to use Promises. Your code inside the setTimeout will be delayed but everything outside of it will continue to run synchronously.

function LastFunction(){    
  firstFunction().then(function(val) {
    console.log(val) 
    return val
  })
}

function firstFunction() {
  var promise = new Promise(function(resolve, reject) {
    setTimeout(function(){
        var something = "something here"
        resolve(something)
    },1000)
  })
  return promise
}
