javascript-lodashHow do I use Lodash to merge two objects in JavaScript?
Using Lodash to merge two objects in JavaScript is simple and straightforward. The _.merge()
method can be used to combine two objects into one.
For example:
let obj1 = {
a: 1,
b: 2
};
let obj2 = {
c: 3,
d: 4
};
let obj3 = _.merge(obj1, obj2);
console.log(obj3);
Output example
{
a: 1,
b: 2,
c: 3,
d: 4
}
The code above uses the _.merge()
method to combine two objects, obj1
and obj2
, into one object, obj3
. The _.merge()
method takes two parameters – the two objects to be merged – and returns a new object with the combined properties.
In the example above, the result is an object with the properties from both obj1
and obj2
.
