Lodash _.conforms() Method - GeeksforGeeks

Last Updated : 03 Nov, 2023

Lodash _.conforms() method of Util is used to create a function that calls the predicate properties of the source with the analogous property values of a stated object, which returns true if all the predicates are true else returns false.

_.conforms(source);

• source (Object): It is the object of property predicates that is to be conformed.

This method returns the new specified function.

Example 1: In this example, we are getting a value in the console that satisfies the given condition in a function.

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

// Initializing an object
let object = [
    { 'x': 2, 'y': 3 },
    { 'x': 5, 'y': 6 }
];

// Calling _.conforms() function with its parameter
let newfunc = _.filter(object, _.conforms({
    'y': function (n) {
        return n > 3;
    }
}));

// Displays output
console.log(newfunc);

Output:

[ { x: 5, y: 6 } ]

Example 2: In this example, nothing is returned as the stated condition is not satisfied.

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

// Initializing an object
let object = [
    { 'GfG': 13, 'geeksforgeeks': 5 },
    { 'GfG': 7, 'geeksforgeeks': 4 }
];

// Calling _.conforms() function with its parameter
let newfunc = _.filter(object, _.conforms({
    'GfG': function (n) {
        return n > 13;
    }
}));

// Displays output
console.log(newfunc);

Output:

[]
