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.
