javascript-lodashHow do I use Lodash to merge two JavaScript objects?
Lodash is a JavaScript library that provides utility functions for common programming tasks. One of these tasks is merging two JavaScript objects. To do this, you can use the _.merge()
function. This function takes two objects as arguments and returns a new object that contains the combined properties of both.
For example:
const obj1 = {
a: 1,
b: 2
};
const obj2 = {
c: 3,
d: 4
};
const mergedObj = _.merge(obj1, obj2);
console.log(mergedObj);
Output example
{
a: 1,
b: 2,
c: 3,
d: 4
}
The _.merge()
function can also take a third argument, which is an object containing options for customizing the merging process. This argument is optional.
Code explanation
const obj1 = { a: 1, b: 2 };
- This is the first object to be merged.const obj2 = { c: 3, d: 4 };
- This is the second object to be merged.const mergedObj = _.merge(obj1, obj2);
- This uses the_.merge()
function to combine the two objects.console.log(mergedObj);
- This logs the result of the merging process.
