How to get the value of a nested object containing array of values

1. You can use Object.keys() like this:

   let Obj = {
       "testname": "Validator",
       "dataTableName": "y",
       "dataColumnName": "y",
       "CheckFilter": "CheckBoxFilter",
       "CheckFilterSettings": {
           "values": [
               "70.00"
           ],
           "hierarchyPaths": [
   
           ]
       }
   }
   
   Object.keys(Obj).map((key) => {
     if (key == 'CheckFilterSettings') {
       Obj[key].values[0] == '70.00' ? console.log('value found') : console.log('value not found');
     }
   });

2. If you want to check that the values array is not empty, and that the path to that array remains constant, you could just use:

   for (var i in Obj) {
       if (Obj[i].CheckFilterSettings.values.length) {
       console.log("Value Found");
       } else {
           console.log("Value Not Found");
       }
   }
   

   Note that this assumes an array of objects, which is not evident from the provided data structure. If that’s the entire object, then try:

   if (Obj.CheckFilterSettings.values.length) {
       console.log("Value Found");
   } else {
       console.log("Value Not Found");
   }

3. Your Obj[i] is itself the key, so, do not call "CheckFilterSettings" on Obj[i] again.

   Check this one-

   var Obj = {
       "testname": "Validator",
       "dataTableName": "y",
       "dataColumnName": "y",
       "CheckFilter": "CheckBoxFilter",
       "CheckFilterSettings": {
           "values": [
               "70.00"
           ],
           "hierarchyPaths": [
   
           ]
       }
   }
   
   for (var i in Obj) {
       if (Obj.hasOwnProperty(i)) {
           if (i === "CheckFilterSettings" && Obj[i].hasOwnProperty("values")) {
               if (Obj[i].values[0] === "70.00") {
                   console.log("Value Found");
               } else {
                   console.log("Value Not Found");
               }
           }
   
       }
   }

4. no need to loop through the object. just simply use es20 feature optional chaining:

   var Obj = {
      "testname":"Validator",
      "dataTableName":"y",
      "dataColumnName":"y",
      "CheckFilter":"CheckBoxFilter",
      "CheckFilterSettings":{
         "values":[
            "70.00"
         ],
         "hierarchyPaths":[
            
         ]
      }
   }
   
   if(Obj?.CheckFilterSettings?.values?.length>0){
   console.log(Obj?.CheckFilterSettings?.values)
   }else {
     //whatever you want
   }

5. It can be simplified, try this…

   if (Obj.CheckFilterSettings && Obj.CheckFilterSettings.values[0] === "70.00"){
       console.log("Value Found");
   } else {
       console.log("Value Not Found");
   }
