Printing object's keys and values

Question

I want to print a key: value pair from javascript object. I can have different keys in my array so cannot hardcode it to object[0].key1

var filters = [{\"user\"         


        

Answer 1

if you want get all keys in array of object, you can try this one mybe

      let temp = []
        let keys = []
        let result = []
        for (let i = 0; i < data.length; i++) {
          temp = Object.keys(data[i])
          for (let j = 0; j < temp.length; j++) {
            if(!keys.includes(temp[j])){
              keys.push(temp[j])
            }

          }
          temp = []
        }

        for (let i = 0; i < data.length; i++) {
            for (let j = 0; j < keys.length; j++) {
              if(data[i][keys[j]] == undefined){
                data[i][keys[j]] = ""
              }

            }

        }
        return data

or this one if you want take the key from same array 2dimension

            function convertObj(arr){
            let arrResult = []
            for (let i = 1; i < arr.length; i++) {
            let obj={}
            for (let j = 0; j < arr[0].length; j++) {
                obj[arr[0][j]] = arr[i][j]

            }
            arrResult.push(obj)  

            }
        return arrResult
        }
