Lodash _.isIncreasing() Method

The Lodash _.isIncreasing() method checks whether the given values are monotonically increasing or not (each argument is greater than the previous argument).

Syntax:

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

Parameters: This method takes n values to checked for increasing order.

Return Value: This method returns a Boolean value (Returns true if the given values are Increasing, else false).

Note: This will not work in normal JavaScript because it requires the lodash.js contrib library to be installed. Lodash.js contrib library can be installed using npm install lodash-contrib.

Example 1:

Javascript

// Defining lodash contrib variable
var _ = require('lodash-contrib');

// Check for increasing order
console.log("The Value is Increasing order : "
    + _.isIncreasing(1, 2, 3, 4));

Output:

The Value is Increasing order : true

Example 2:

Javascript

// Defining lodash contrib variable
var _ = require('lodash-contrib');

// Check for increasing order
console.log("The Value is Increasing : "
    + _.isIncreasing(3, 2, 1, 2));

Output:

The Value is Increasing : false

Example 3:

Javascript

// Defining lodash contrib variable
var _ = require('lodash-contrib');

// Check for increasing order
console.log("The Value is Increasing : "
    + _.isIncreasing('a', 'b'));

console.log("The Value is Increasing : "
    + _.isIncreasing('c', 'b', 'a'));

Output:

The Value is Increasing : true
The Value is Increasing : false

Example 4:

Javascript

// Defining lodash contrib variable
var _ = require('lodash-contrib');

// Check for increasing order
console.log("The Value is Increasing : "
    + _.isIncreasing("Geeks", "GFG"));

console.log("The Value is Increasing : "
    + _.isIncreasing('g', 'G'));

Output:

The Value is Increasing : false
The Value is Increasing : false
