Lodash is a JavaScript library that provides utility functions for common programming tasks. It can be used to filter a nested array of objects in JavaScript.
Here is an example of how to use Lodash to filter a nested array of objects:
const data = [
{
id: 1,
name: 'John',
age: 20
},
{
id: 2,
name: 'Jill',
age: 30
},
{
id: 3,
name: 'Jack',
age: 25
}
]
const result = _.filter(data, { age: 25 });
console.log(result);
Output example
[
{
id: 3,
name: 'Jack',
age: 25
}
]
The code above uses Lodash's _.filter()
function to filter the data
array. It takes two arguments: the array to be filtered, and an object containing the filter criteria. In this case, the filter criteria is { age: 25 }
, which will filter the array to only include objects with an age
of 25
. The result is stored in the result
variable, which is then logged to the console.
