How to access object array using javascript with variable

Question

var dict = {
  "configMigratedTo": {
        "message": "Migrated configuration to configurator: $1"
    }
}
var parametersForTranslation = {};
function __tr(src, params) {
  parametersForTranslation[src] = params;
  return buildMessage(src);
}

function buildMessage(src){
    var message=dict[src] ? dict[src].message : src
    console.log(message);
    var messageArray = message.split("$");
    var output = "";
    messageArray.forEach(function(elem, index){
        if(index === 0){
            output += elem;
        }else{
            // get variable and index
            var paramIndex = configMigratedTo.substring(0, 1);
            var paramValue = parametersForTranslation[src][paramIndex-1];
            output += paramValue;
            output += configMigratedTo.substring(1);
        }
    });
    return output;
}
__tr("configMigratedTo", [2]);
console.log(buildMessage("configMigratedTo"));

i want get result like __tr("configMigratedTo", [2]); then it will give me

Migrated configuration to configurator: 2

i do not know where is wrong in my code

@LouysPatriceBessette it's a function, defined above, in code. — tao

basically, it means find translation according to the key...__tr means translation — 12345GG

Ha. ok. But you mess on the source. You want to access configMigratedTo in the dict object. It should be something like : dict.configMigratedTo.message to get the value Migrated configuration to configurator: $1... Now I really don't know if the $1 will taken in account as a variable... That depends on the buildMessage() function And I can't tell just like this. — Louys Patrice Bessette

Well, before you can play around with programming logic you need a solid foundation of programming (JavaScript, in this case) basic concepts. And from trying to access a variable which has not yet been defined it looks like you should focus on the latter. Do you understand the difference between the missing variable configMigratedTo var and the existing property on the dict object? — tao

Try this one. Hope it helps!

var dict = {
  "configMigratedTo": {
        "message": "Migrated configuration to configurator: $1"
    }
}

function __tr(src, params) 
{
    for (var key in dict)
  {
    if (key === src)
    {
        var message = dict[key].message;
        return message.substring(0, message.length - 2) + params[0];
    }
  }
  return;
}


console.log(__tr("configMigratedTo", [2]))

Would that be enought?

var dict = {
  "configMigratedTo": {
        "message": "Migrated configuration to configurator: "
    }
}

function buildMessage(src,param){
    var output = dict[src].message + param;
    return output;
}

console.log(buildMessage("configMigratedTo",2));

You are overcomplicating this, it's much easier using a regex and passing a function as replacer

var dict = {
  "configMigratedTo": {
    "message": "Migrated configuration to configurator: $1"
  }
}
function __tr(src, params) {
  if (! dict[src]) return src;
  if (! /\$0/.test(dict[src].message)) params.unshift('');
  return dict[src].message.replace(/\$(\d)+/g, (orig, match) => params[match] || orig);
}

console.log(__tr("configMigratedTo", [2]));
