This is the response array for my api post request. i have a empty array and i want to check if the image name is same for another list. i want to parse that bbox value in list. Needed format:

[
{
"name":"1.png",
"confidence":[[0.9],[0.9],[0.9],[0.9],[0.9]],
"bbox":[[160.0, 916.0, 169.0, 925.0],[107.0, 890.0, 112.0, 896.0],[119.0, 871.0, 123.0, 873.0],[343.0, 703.0, 346.0, 705.0]]

}
]

I didn't have a clue how to iterate over this to get the required format.kindly guide me to approach this problem

CodePudding user response：

You can try the below code to get the required output. I have written captured each manipulation of the response in a separate variable for better understanding, but feel free to refactor to lesser lines of code. Do let me know if it fulfills your requirement.

const flatArray = [].concat.apply([], response);

const flatMap = flatArray.reduce((accum, e) => {
  if (!accum[e.name]) {
    accum[e.name] = {
      name: e.name,
      bbox: [e.bbox],
      confidence: [[e.confidence]]
    };
  } else {
    accum[e.name].confidence.push([e.confidence]);
    accum[e.name].bbox.push(e.bbox);
  }
  return accum;
}, {});

console.log(Object.values(flatMap));
