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 )

  • 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.

// 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', 'GeeksforGeeks']);

Output:

Example 2:

Javascript




// Requiring lodash library
