This method can be used to bisect arrays of objects instead of being limited to simple arrays of primitives. For example, given the following array of objects:var data = [ {date: new Date(2011, 1, 1), value: 0.5}, {date: new Date(2011, 2, 1), value: 0.6}, {date: new Date(...
.NET includes predefined IComparer implementations listed in the following table. Expand table ImplementationDescription System.Collections.CaseInsensitiveComparer Compares any two objects, but performs a case-insensitive comparison of strings. Comparer.Default Compares any two objects by using the sorting ...
reduce() 方法对数组中的每个元素按序执行一个提供的 reducer 函数,每一次运行 reducer 会将先前元素的计算结果作为参数传入,最后将其结果汇总为单个返回值。

Sorts a range of elements in a pair of one-dimensional Array objects (one contains the keys and the other contains the corresponding items) based on the keys in the first Array using the IComparable implementation of each key. Sort(Array, Int32, Int32) Sorts the elements in a range of...
Write a JavaScript function that returns the index of a given element if it exists, or -1 if it does not. Write a JavaScript function that iterates through an array to find and return true if a particular element is found. Write a JavaScript function that searches an array of objects for...
