Underscore.JS——isArray 方法
语法
_.isArray(argument)
isArray 方法检查参数是否是数组。请参见下面的示例:
示例
var _ = require('underscore'); //Example 1: Check if argument passed is an array var result = _.isArray({ name : 'Sam'}); console.log(result); //Example 2: Check if argument passed is an array result = _.isArray([1, 2, 3 ]); console.log(result);
将以上程序保存在tester.js 中。运行以下命令来执行此程序。
命令
\>node tester.js
输出
false true
