[ 8, 9 ]
Example 2: In this example, we are using the lodash _.prototype[Symbol.iterator]() method.

Output:
[ 'Beginner', 'for', 'Beginner' ]
Example 3: In this example, we are using the lodash _.prototype[Symbol.iterator]() method.
Javascript
// Requiring lodash libraryconst _ = require('lodash');// Calling [Symbol.iterator]() method and// comparing it with wrapped value_("Beginner")[Symbol.iterator]() === _("Beginner");// Wrapper objectlet obj = Array.from(_("Beginner"));// Displays outputconsole.log(obj[0]);console.log(obj[1]);console.log(obj[2]);console.log(obj[3]); |
