In an array like below:
[{
"sport" : "Cricket",
"score" : "22.45"
},
{
"sport" : "Tennis",
"score" : "-12"
}]
I would like to iterate the JSON and find the array with lowest value of score. In this case get
{
"sport" : "Tennis",
"score" : "-12"
}
Sort in ascending order based on the score and return the first object
var a = [{
"sport": "Cricket",
"score": "22.45"
},
{
"sport": "Tennis",
"score": "-12"
}
];
console.log(a.sort((a, b) => a.score - b.score)[0])
You should use parseInt:
var arr = [{
"sport" : "Cricket",
"score" : "22.45"
},
{
"sport" : "Tennis",
"score" : "-12"
},
{
"sport" : "Tennis",
"score" : "-12000"
}];
var res = arr.reduce((a,c) => parseInt(c.score) < parseInt(a.score) ? c : a);
Try this to Get array from JSON Array with lowest key's value
let myArray =[{
"sport" : "Cricket",
"score" : "22.45"
},
{
"sport" : "Tennis",
"score" : "-12"
},
{ "sport" : "Tennis", "score" : "-12000" }]
let minOfArray =myArray.reduce(function(prev, curr) {
return parseInt(prev.score) < parseInt(curr.score) ? prev : curr;
});
console.log(minOfArray);
{ "sport" : "Tennis", "score" : "-12000" }You can use reduce to iterate on your items and get the lowest score:
const data = [{
"sport" : "Cricket",
"score" : "22.45"
}, {
"sport" : "Tennis",
"score" : "-12"
}];
const result = data.reduce((acc, x) => x.score < acc.score ? x : acc, data[0]);
console.log(result);
