如何从一组特定的数字中找到最接近的较高数字：JavaScript？
我们有一组数字，我们的要求是找到与作为函数输入提供的特定数字相同或最接近的较高数字键。
这组数字定义为-
const numbers = {
A:107,
B:112,
C:117,
D:127,
E:132,
F:140,
G:117,
H:127,
I:132,
J:132,
K:140,
L:147,
M:117,
N:127,
O:132
};示例
为此的代码将是-
const numbers = {
A:107,
B:112,
C:117,
D:127,
E:132,
F:140,
G:117,
H:127,
I:132,
J:132,
K:140,
L:147,
M:117,
N:127,
O:132
};
const nearestHighest = (obj, val) => {
let diff = Infinity;
const nearest = Object.keys(obj).reduce((acc, key) => {
let difference = obj[key] - val;
if (difference >= 0 && difference < diff) {
diff = difference;
acc = [key];
}
return acc;
}, [])
return nearest;
};
console.log(nearestHighest(numbers, 140));输出结果
控制台中的输出将是-
['F']
