max(...arr); const result = arr.indexOf(maxNumber); console.log(result); Output: 2 In the example above, we have used the Math.max(..arr) to get the max value of an array, then we have passed the max value to the Array.indexOf() method to get index of it. The Math.max(...
在极少数情况下,数组的下限等于 Int32.MinValue (0x80000000) 且 value 找不到 ,此方法将 Int32.MaxValue 返回(0x7FFFFFFF) 。 此方法是 O (n) 操作,其中 n 是Length 的array。 另请参阅 LastIndexOf 适用于 .NET 9 和其他版本 产品版本 .NET Core 1.0, Core 1.1, Core 2.0, Core 2.1, Core...
findIndex((value)=>value.id==4); console.log(i);// 3 var i2=bookArr.findIndex((value)=>value.id==100); console.log(i2);// -1 filter() filter()与find()使用方法也相同。同样都接收三个参数。不同的地方在于返回值。filter()返回的是数组,数组内是所有满足条件的元素,而find()只返回第...
