Can you help me identify the array element with the highest 'conversion' value?
var barTextData = [
{
term: "Roof",
clicks: 11235,
conversion: 3.12
}, {
term: "Snow",
clicks: 6309,
conversion: 4.45
}, {
term: "Chains",
clicks: 4479,
conversion: 4.33
}
]
Additionally, I need to retrieve the corresponding 'term' string.
One way to solve this is by using a basic iteration:
let maxNum = 0, word = "";
for (let index = 0; index < data.length; index++) {
if (data[index].value > maximum) {
maxNum = data[index].value;
phrase = data[index].term;
}
}
To find the item with the highest conversion in an array, loop through the array and compare each item's conversion value to the current highest found value. If the conversion of the current item is higher, replace the highest value with the current item. By the end of the loop, you will have the item with the highest conversion saved.
Remember to compare based on the conversion property but save the entire item so that you can access other properties like term.
var barTextData = [{
term: "Roof",
clicks: 11235,
conversion: 3.12
}, {
term: "Snow",
clicks: 6309,
conversion: 4.45
}, {
term: "Chains",
clicks: 4479,
conversion: 4.33
}];
// Find the item with the highest conversion
var highest = null;
barTextData.forEach(function(item) {
if (!highest || item.conversion > highest.conversion) {
highest = item;
}
});
if (highest) {
document.getElementById("result").textContent = JSON.stringify(highest);
} else {
document.getElementById("result").textContent = "No item found.";
}<pre id="result"></pre>To find the maximum value in an array, you can use the method of sorting it and selecting the first element
var highestValue = dataList.sort(function(a, b) {
return a.value < b.value;
})[0];
console.log(highestValue.item);
To solve this problem, you can utilize Array's reduce method:
var maxBarTextObject = barTextData.reduce(function(currentMax, current) {
if (!currentMax) {
return currentMax;
}
return (current.conversion > currentMax.conversion) ? current : currentMax;
});
If this code is running on the client side, it's important to note that Array.prototype.reduce is supported by all major browsers except IE7 and 8. More information about browser compatibility can be found here.
