语法:arr.reverse()var array1 = ['one', 'two', 'three'] array1.reverse() console.log(array1) // 输出: [ 'three', 'two', 'one' ] 11. 数组的合并 concat():该方法用于合并两个或更多数组,并返回合并后的新数组,原数组不会改变。
1functioncompare(value1, value2){2returnvalue2 -value1;3} 由于比较函数是通过返回一个小于零、等于零或大于零的值来影响排序结果,因此减法操作就可以适当处理所有这些情况。 小结 1.sort()方法单独引用并不稳定和严谨,所以sort()方法可以返回一个比较函数来作为参数。

二、Array.property.sort() 含义:sort方法基于原地算法实现数组排序,直接对数据进行排序 参数:sort(compare(a,b)),指定顺序对数组进行排序,不写参数的时候,默认会将原数据转换成字符串按照字符的Unicode编码进行排序。 compare(a,b)中,a、b都是比较参数,当 a-b>0 ,交换位置 a-b=0,位置不变 a-b<0,位置...
对于以JavaScript为主的Node.js开发者来说,你可能不太熟悉类似于“std::wx::y”或“&xyz”之类的表述,但是没关系,我会详细解释。 与JavaScript和Node.js相比,Rust是一门较为低级的语言。这意味着,你需要熟悉计算机的工作原理,才能真正理解Rust。而Node.js更为高级,通常接触不到这些表述。
var arr = new Float32Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] ); // Copy the first two elements to the last two elements: arr.copyWithin( 3, 0, 2 ); var v = arr[ 3 ]; // returns 1.0 v = arr[ 4 ]; // returns 2.0 When a target, start, and/or end index is negative, ...
