Use this function

var replaceText = function () {
    var inputval = document.getElementById('first_text').value;
    var arr = {
        "going": "GNG",
        "used to": "UD",
        "as soon as possible": "ASAP",
        "to do fast": "tdf"
    }

    for(var key in arr) {
        if (typeof (arr[key]) !== "undefined") inputval = inputval.replace(key, arr[key])
    }
    document.getElementById("second_text").value = inputval;
}

Why the undefined test? You're not going to get an undefined in a for..in loop (unless you've explicitly assigned a key to undefined).

@nnnnnn Sorry my bad, it should be if(arr.hasOwnProperty(key)). This ables to determine whether an object has the specified property as a direct property of arr object

Do something like this. Define word replace as map.

var wordmap = {
  going: 'GNG',
  'used to': 'UD',
  'as soon as possible': 'asap',
  'to do fast': 'tdf',
  ..

}

and define function that iterates every word in the input string.

function replace( text ) {
    var input = text.split(' ');
    var outputval = []
    for (var i in input) {
       outputval.push( wordmap[input[i]] || input[i] )
    }
    return outputval.join(' ');
}

And use it like this

var output = replace( document.getElementById('first_text').value );
