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[Symbol.iterator]() method of Sequence in lodash is used to permit the wrapper to be iterable.
Syntax:
_.prototype[Symbol.iterator]()
Parameters: This method doesn’t accept any parameter.
Return Value: This method returns the lodash wrapper object.
Example 1:
Javascript
// Requiring lodash library const _ = require( 'lodash' ); // Creating wrapped variable var wrapr = _([8, 9]); // Calling [Symbol.iterator]() method wrapr[Symbol.iterator]() === wrapr; let obj = Array.from(wrapr); // Displays output console.log(obj); |
Output:
[ 8, 9 ]
Example 2:
Javascript
// Requiring lodash library const _ = require( 'lodash' ); // Creating wrapped variable var wrapr = _([ 'Geeks' , 'for' , 'Geeks' ]); // Calling [Symbol.iterator]() method wrapr[Symbol.iterator]() === wrapr; let obj = Array.from(wrapr); // Displays output console.log(obj); |
Output:
[ 'Geeks', 'for', 'Geeks' ]
Example 3:
Javascript
// Requiring lodash library const _ = require( 'lodash' ); // Calling [Symbol.iterator]() method and // comparing it with wrapped value _( "Geeks" )[Symbol.iterator]() === _( "Geeks" ); // Wrapper object let obj = Array.from(_( "Geeks" )); // Displays output console.log(obj[0]); console.log(obj[1]); console.log(obj[2]); console.log(obj[3]); |
Output:
G e e k
