Lodash _.prototype.commit() Method

Lodash _.prototype.commit() method is used to implement the chain sequence type and find the wrapped output.

Syntax:

_.prototype.commit();

Parameters:

This method does not accept any parameter.

Return Value:

This method returns the new lodash wrapper instance.

Example 1: In this example, we are pushing an element into a given array and committing the array with the help of the lodash _.prototype.commit() method.

// Requiring lodash library
const _ = require('lodash');

// Creating an array of integers
let arr = [5, 6];

// Pushing an integer into the array
let wrapper = _(arr).push(7);

// Using the commit() method
wrapper = wrapper.commit();

// Displays output
console.log(arr);

Output:

[ 5, 6, 7 ]

Example 2: In this example, we are pushing an element into a given array and committing the array with the help of the lodash _.prototype.commit() method.

// Requiring lodash library
const _ = require('lodash');

// Creating an array of strings
let arr = ['Geeks', 'for'];

// Pushing a string into the array
let wrapper = _(arr).push('Geeks');

// Using the commit() method
wrapper = wrapper.commit();

// Displays output
console.log(arr);

Output:

[ 'Geeks', 'for', 'Geeks' ]

Example 3: In this example, the wrapper object is returned.

// Requiring lodash library
const _ = require('lodash');

// Using the commit() method
let obj = _(['G', 'f']).reverse().commit();

// Displays output
console.log(obj);

Output:

LodashWrapper {
  __wrapped__: [ 'f', 'G' ],
  __actions__: [],
  __chain__: false,
  __index__: 0,
  __values__: undefined
