Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

The _.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:

Javascript




// Requiring lodash library
const _ = require('lodash');
  
// Creating an array of integers
var arr = [5, 6];
  
// Pushing an integer into the array
var wrapper = _(arr).push(7);
   
// Using the commit() method
wrapper = wrapper.commit();
  
// Displays output
console.log(arr);


Output:

[ 5, 6, 7 ]

Example 2:

Javascript




// Requiring lodash library
const _ = require('lodash');
  
// Creating an array of strings
var arr = ['Geeks', 'for'];
  
// Pushing a string into the array
var 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.

Javascript




// Requiring lodash library
const _ = require('lodash');
  
// Using the commit() method
obj = _(['G', 'f']).reverse().commit();
  
// Displays output
console.log(obj);


Output:

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