JavaScript正则表达式 一.构造函数创建正则表达式 1.正则表达式用于定义一些字符串的规则,计算机可以根据正则表达式,来检查一个字符串是否符合规则,可以将字符中符合规则的内容提取出来。在构造函数中可以传递一个匹配模式作为第二个参数(i 忽略大小写、g 全局匹配)。 2.test()方法,使用这个方法可以用来检查一个字符串...
[2,3],{name:'John'}];constarr3=[1,[2,3],{name:'Jane'}];console.log(deepArrayEqual(arr1,arr2));// trueconsole.log(deepArrayEqual(arr1,arr3));// false 在上述示例中,deepArrayEqual函数会递归比较两个数组的每个元素的值,包括嵌套的数组和对象。如果两个数组是相等的,则返回true,否则返回...
