Required Output:

All Im trying to do is collect all the answerOptionCodesDes and put it in a single object.
Please help, Thanks

You could use reduce to return that result:
let result = model.questionnaires.reduce(
(acc, q) => q.questionAndAnswerOptions.reduce(
(acc, o) => Object.assign(acc, o.answerOptionCodesDes), acc), {});
let model = {
"questionnaires": [

"typeCode": "201",
"questionAndAnswerOptions": [

"questionCode": "q0101",
"questionTypeCode": "100",
"answerOptionCodes": [
"010101",
"010102",
"010103"
],
"questionCodeDes": " cat 1 question 1",
"answerOptionCodesDes": {
"010101": "T?m parami riske ederek getirilerimi iyilestirmeye ?alisirim",

First you define the object you want all the values in:
var mapped = {};
Then loop over every entry in the model-array, and in that loop, loop again through every entry in the questionAndAnswerOptions-array.
Then you can add the objects in those arrays to the mapped-variable with Object.assign
model.questionnaires.forEach(function(questionnaire){
questionnaire.questionAndAnswerOptions.forEach(function(qAndA){
Object.assign(mapped,qAndA.answerOptionCodesDes);
});
});
