Let's say I have the following array of objects:
[
{ name: 'january', score: 3.02 },
{ name: 'february', score: 1.02 },
{ name: 'march', score: 0 },
{ name: 'april', score: 12 },
]
What would be the quickest method for extract the position (index) of the element of the object with the highest score value...so, in the above case, the value would be index 3...
N.B. Scores are dynamic, and the "winning" element is the highest value...
You could get the keys and reduce the indices by checking the score.
var data = [{ name: 'january', score: 3.02 }, { name: 'february', score: 1.02 }, { name: 'march', score: 0 }, { name: 'april', score: 12 }],
index = [...data.keys()].reduce((a, b) => data[a].score > data[b].score ? a : b);
console.log(index);
var index to be?
3, because it has the hightest score of 12.fuzzyRegexScore and not score - a quick edit and boom! Works. Thank you.Try this. Use javascript max and map function to get value of index
var data = [
{ name: 'january', score: 3.02 },
{ name: 'february', score: 1.02 },
{ name: 'march', score: 0 },
{ name: 'april', score: 12 }
];
var maxValue =
Math.max.apply(Math, data.map(function(row,index) { return index; }))
console.log(maxValue)2) I think this will also give you correct result
var data = [
{ name: 'april', score: 1 },
{ name: 'january', score: 3.02 },
{ name: 'february', score: 11.02 },
{ name: 'march', score: 2 }
];
var maxValue = Math.max.apply(Math, data.map(function(row) { return row.score; }))
var key = data.findIndex((row,index)=>{ if(row.score ===maxValue){return true}})
console.log(key)
var data = [
{ name: 'january', score: 3.02 },
{ name: 'february', score: 1.02 },
{ name: 'march', score: 0 },
{ name: 'april', score: 12 },
];
var resultValue = null;
var tempValue = Number.NEGATIVE_INFINITY;
data.forEach(function(element, index) {
if(element.score > tempValue) {
tempValue = element.score;
resultValue = index;
}
});
console.log(resultValue);
Number.NEGATIVE_INFINITY
