Lodash _.conformTo() Method

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, collection, strings, objects, numbers etc.

The _.conformsTo() method checks if object conforms to source by invoking the predicate properties of source with the corresponding property values of object and this method is equivalent to _.conforms when source is partially applied.

Syntax:

_.conformsTo(object, source)

Parameters: This method accepts two parameters as mentioned above and described below:

• object: It is the object that the method is to inspect.
• source: It is the object of property predicates to conform to.

Return Value: This method returns the object of property predicates to conform to.

Example 1: Here, const _ = require(‘lodash’) is used to import the lodash library in the file.

// Requiring the lodash library
const _ = require("lodash");

// Original array
var object = { 'p': 11, 'q': 9 };

// Using the _.conformsTo() method
let conform_data =  _.conformsTo(object, {
    'q': function

    (n) { return n > 1; }
});

// Printing the output
console.log(conform_data);

Output:

true

Example 2:

// Requiring the lodash library
const _ = require("lodash");

// Original array
var object = { 'x': 1, 'y': 3 };

// Using the _.conformsTo() method

let conform_data =  _.conformsTo(object, {
    'q': function

    (n) { return n > 3; }
});

// Printing the output
console.log(conform_data);

Output:

false

Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
