how to use the ismatch function from lodash in javascript

The _.isMatch(object, source) function from Lodash is used to check if an object conforms to a source by invoking _.conformsTo(object, _.conforms(source)).

Here's an example of how to use the _.isMatch function:

index.tsx
const _ = require('lodash');

const object = { 'a': 1, 'b': 2, 'c': 3 };
const source = { 'b': 2 };

console.log(_.isMatch(object, source)); // true
149 chars
7 lines

In this example, the _.isMatch function is used to check if object matches the source. Since object has a key-value pair b: 2, which matches the source, the _.isMatch function returns true.

Note that the _.isMatch function does not handle nested objects. If you need to check nested objects, you can use _.matches instead of _.conforms.

index.tsx
const _ = require('lodash');

const object = { 'a': { 'b': 2 } };
const source = { 'a': { 'b': 2 } };

console.log(_.isMatch(object, source)); // false
console.log(_.isMatch(object, _.matches(source))); // true
211 chars
8 lines

In this example, the source and object have the same structure, but the _.isMatch function returns false because it does not handle nested objects. We can use _.matches(source) to create a function that returns true if the object matches the source, and then pass that function to _.conformsTo(object, ...) to check if the object conforms to the source.
