Can anyone guide me through sorting a JSON data into an array based on numeric value, and then explain how to efficiently access that information?
{"362439239671087109":{"coins":19},"178538363954003968":{"coins":18},"234255082345070592":{"coins":137}}
The unconventional numbers represent Discord user IDs.
Before anything else, create an associative array. If the JSON data is coming from the backend, like in PHP for example, you can utilize functions to sort arrays. Take a look at this resource for more information on sorting arrays in PHP: http://php.net/manual/en/array.sorting.php For additional insights, check out this thread discussing how to convert JavaScript objects with numeric keys into arrays: Converting JavaScript object with numeric keys into array
let obj = {"362439239671087109":{"coins":19},"178538363954003968":{"coins":18},"234255082345070592":{"coins":137}};
let keys = Object.keys(obj);
keys.sort(function(x,y){return obj[x].coins-obj[y].coins});
console.log(keys);
// Have a look at this code snippet that effectively handles large numbers by treating them as strings.
var data = {
"362439239671087109": {
"coins": 19
},
"178538363954003968": {
"coins": 18
},
"234255082345070592": {
"coins": 137
}
};
function padWithZeros(s) {
return ("000000000000000000000" + s).substr(-20);
}
var keys = Object.keys(data);
keys.sort(
function(x, y) {
var str1 = padWithZeros(data[x].coins);
var str2 = padWithZeros(data[y].coins);
if (str1 === str2) {
return 0;
}
if (str1 > str2) {
return 1;
} else {
return -1;
}
});
