javascript-lodashHow can I use Lodash to remove undefined values from an object in JavaScript?
Lodash provides a utility function _.omitBy
to remove undefined values from an object. The following example code will demonstrate how to use it:
const _ = require('lodash');
const obj = {
a: 'hello',
b: undefined,
c: 'world'
};
const modified = _.omitBy(obj, _.isUndefined);
console.log(modified);
Output example
{ a: 'hello', c: 'world' }
The code does the following:
require
s the lodash library.- Creates an object
obj
with two defined and one undefined property. - Uses
_.omitBy
to remove all properties with an undefined value. console.log
s the modified object.
