使用组合的嵌套数组过滤器过滤JSON数组

Question

I'm writing a JS code that has to filter JSON data based on a condition. I've posted a question yesterday but without trying anything at How to filter data from a json response , it was down voted and since I didn't try anything I am good with it. I've tried using the filter, but unfortunately I've got an array with in array and here I'm stuck. Here is my code.

var arr2 = [
  [{
    "max": "0.685",
    "target_state": "6",
    "ingredients": "a",
    "rule_no": "7",
    "id": "18"
  }, {
    "max": "14",
    "target_state": "6",
    "ingredients": "b",
    "rule_no": "7",
    "id": "17"
  }],
  [{
    "max": "14",
    "target_state": "7",
    "ingredients": "b",
    "rule_no": "8",
    "id": "19"
  }, {
    "max": "1.36",
    "target_state": "7",
    "ingredients": "a",
    "rule_no": "8",
    "id": "20"
  }]
];

var result = arr2.reduce(function(a, b) {
    return a.concat(b);
  })
  .filter(function(obj) {
    return (obj.max == 0.685 && obj.ingredients === "a")
  });

alert(JSON.stringify(result[0].target_state));

when I run this code, I get the result as "6".

But here my condition is something like this ((obj.max == 0.685 && obj.ingredients === "a") && (obj.max == 14 && obj.ingredients === "b")) , but this is not returning anything.

Here the expected output is "6" .

Here is a working fiddle https://jsfiddle.net/vjt45xv4/14/

Please let me know where am I going wrong and how can I fix this.

Thanks

I think I understand what you are trying to achieve here.

How about the following one? It worked for me.

var result = arr2
  .filter(function(objs) {
    return ((objs.find((obj) => obj.ingredients === "a" ).max == 0.685) 
&& (objs.find((obj) => obj.ingredients === "b" ).max == 14));
  })
  .reduce(function(a, b) {
    return a.concat(b);
  });
