Grouping JSON by values
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}.`) }) });
