Grouping JSON by values

Question

Using the Lever job posting API, I\'m getting JSON results sorted by location, and I\'m trying to figure out how to group all those results by \"team\" within the results, l

Answer 1

Assume , the JSON output is

outJSON= 
 [ {
      team: "TeamA",
      name: "Ahmed",
      field3:"val3"
  }, 
{
      team: "TeamB",
      name: "Ahmed",
      field3:"val43"
  }, 
{
      team: "TeamA",
      name: "Ahmed",
      field3:"val55"
  }, 


]

Then see the groupBy function in the DEMO below:

DEMO :

outJSON= [ {team: "TeamA",name: "Ahmed",field3:"val3"}, {team: "TeamB",name: "Ahmed",field3:"val43"}, {team: "TeamA",name: "Ahmed",field3:"val55"} ]

var groupBy = function(xs, key) {
  return xs.reduce(function(rv, x) {
    (rv[x[key]] = rv[x[key]] || []).push(x);
    return rv;
  }, {});
};
var groubedByTeam=groupBy(outJSON, 'team')
console.log(groubedByTeam);

Then , if you want to loop through categories (teams), get all categories in array :

Object.keys(groubedByTeam) // return ["TeamA","TeamB"]

then :

  Object.keys(groubedByTeam).forEach(function(category){
     
       console.log(`Team ${category} has ${groubedByTeam[category].length} members : `);
        groubedByTeam[category].forEach(function(memb,i){
              console.log(`---->${i+1}. ${memb.name}.`)
       })
  });
