javascript-lodashHow do I use Lodash to merge two objects in JavaScript?
Using Lodash to merge two objects in JavaScript is very easy. All you need to do is call the _.merge()
method, passing in the two objects as arguments.
let obj1 = {
name: 'John',
age: 30
};
let obj2 = {
name: 'Jane',
city: 'New York'
};
let mergedObj = _.merge(obj1, obj2);
console.log(mergedObj);
Output example
{
name: 'Jane',
age: 30,
city: 'New York'
}
The _.merge()
method will merge the two objects, overriding any duplicate keys with the values from the second object. In this example, the name
key was overridden with the value from obj2
.
It's also possible to pass in a third argument to the _.merge()
method, which is a customizer function. This customizer function allows you to customize the merging process, and can be used to control how the two objects are merged.
For more information, see the Lodash documentation.
