Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.
The _.rest() method is used to create a function that calls the given func with the this binding of the created function along with an array of arguments from the start position and beyond.
Syntax:
_.rest( func, start )
Parameters: This method accepts two parameters as mentioned above and described below:
- func: It is the function that is used to apply a rest parameter to.
- start: It is the start position of the rest parameter. It is an optional parameter.
Return Value: This method returns the new function.
Example 1:
Javascript
// Requiring lodash library const _ = require( 'lodash' ); // Using the _.rest() method // with its parameter var write = _.rest( function (author, portal) { return author + portal; }, [1]); // Calling write with its values write([ 'Nidhi' , 'neveropen' ]); |
Output:
Nidhi,neveropen
Example 2:
Javascript
// Requiring lodash library const _ = require( 'lodash' ); // Using the _.rest() method // with its parameter var called = _.rest( function (who, whom) { return who + ' ' + _.initial(whom).join( ', ' ) + (_.size(whom) > 2 ? ', and ' : '' ) + _.last(whom); }); // Calling called with values called( 'Teacher called' , 'nidhi' , 'nisha' , 'preeti.' ); |
Output:
Teacher called nidhi, nisha, and preeti.
