Underscore.js _.seq() 方法
_.seq()方法检查每个参数是否严格相等 (===)。因此,相应地返回一个布尔值。
句法:
_.seq( val1, val2, ..., valn );
参数:此方法需要 n 个值对其进行操作。
返回值:此方法返回一个布尔值。
注意:这在普通 JavaScript 中不起作用,因为它需要安装 underscore.js contrib 库。
underscore.js contrib 库可以使用npm install underscore-contrib –save 安装。
示例 1:
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.seq( 6, 6, 6 );
console.log("Each of the arguments is equal to others :", eq);
输出:
Each of the arguments is equal to others : true
示例 2:
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.seq( "gfg", "gfg", "gfg" );
console.log("Each of the arguments is equal to others :", eq);
输出:
Each of the arguments is equal to others : true
示例 3:
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.seq( 1, "1", 1 );
console.log("Each of the arguments is equal to others :", eq);
输出:
Each of the arguments is equal to others : false
示例 4:
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.seq( 1, 12, 1 );
console.log("Each of the arguments is equal to others :", eq);
输出:
Each of the arguments is equal to others : false
