Consider the following array:
[{
"activity" : "Hiking",
"level" : "8.5"
},
{
"activity" : "Swimming",
"level" : "-3.2"
}]
I want to loop through the JSON data and identify the object with the lowest value for level. In this example, I should retrieve
{
"activity" : "Swimming",
"level" : "-3.2"
}
Organize in an ascending order depending on the points and retrieve the initial element
var b = [{
"activity": "Running",
"points": "18"
},
{
"activity": "Swimming",
"points": "9"
}
];
console.log(b.sort((c, d) => c.points - d.points)[0])The recommended method to use in this scenario is parseInt:
let data = [{
"subject" : "Math",
"result" : "95"
},
{
"subject" : "History",
"result" : "75"
},
{
"subject" : "Science",
"result" : "82"
}];
let highestResult = data.reduce((prev, current) => parseInt(current.result) > parseInt(prev.result) ? current : prev);
Follow this code snippet to extract an array from a JSON Array with the 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);To find the lowest score among your items, you can utilize the reduce method in JavaScript:
const data = [{
"sport" : "Football",
"score" : "14.75"
}, {
"sport" : "Basketball",
"score" : "9.8"
}];
const result = data.reduce((acc, x) => x.score < acc.score ? x : acc, data[0]);
console.log(result);I am currently attempting to retrieve data from a remote location using a JQuery post method. It works perfectly fine when I directly input the data to be posted, but for some reason, it fails when I store the JSON in a JavaScript variable and pass it in. ...
