Underscore.js _.seq() Method

The _.seq() method checks whether each of the arguments is strictly equal (===) to each other. Hence, returning a boolean correspondingly.

Syntax:

_.seq( val1, val2, ..., valn );

Parameters: This method takes n values to operate on them.

Return Value: This method returns a boolean.

Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed.

underscore.js contrib library can be installed using:

npm install underscore-contrib –save

Example 1: In this example, we will see the use _.seq() method.

javascript

// Defining underscore contrib variable
const _ = require('underscore-contrib');

let eq = _.seq(6, 6, 6);

console.log("Each of the arguments is equal to others :", eq);

Output:

Each of the arguments is equal to others : true

Example 2: In this example, we will see the use _.seq() method.

javascript

// Defining underscore contrib variable
const _ = require('underscore-contrib');

let eq = _.seq("gfg", "gfg", "gfg");

console.log("Each of the arguments is equal to others :", eq);

Output:

Each of the arguments is equal to others : true

Example 3: In this example, we will see the use _.seq() method.

javascript

// Defining underscore contrib variable
const _ = require('underscore-contrib');

let eq = _.seq(1, "1", 1);

console.log("Each of the arguments is equal to others :", eq);

Output:

Each of the arguments is equal to others : false

Example 4: In this example, we will see the use _.seq() method.

javascript

// Defining underscore contrib variable
const _ = require('underscore-contrib');

let eq = _.seq(1, 12, 1);

console.log("Each of the arguments is equal to others :", eq);

Output:

Each of the arguments is equal to others : false
