Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.
The _.spread() method is used to create a function that calls the given function as parameter using the this binding of the create function, along with an array of arguments. It is based on the spread operator in JavaScript.
Syntax:
_.spread( func, start )
Parameters: This method accept two parameters as mentioned above and described below:
- func: It is the function that is used to spread arguments over.
- start: It is the start position of the spread. It is an optional parameter. The default value is 0.
Return Value: This method returns the new function.
Example 1:
Javascript
// Requiring lodash library const _ = require('lodash'); Â Â // Using the _.spread() method with its parameter var write = _.spread(function(author, portal) { Â Â return author + ' writes for ' + portal + '!'; }); Â Â // Calling write with its values write(['Nidhi', 'neveropen']); |
Output:
Nidhi writes for neveropen!
Example 2:
Javascript
// Requiring lodash library const _ = require('lodash'); Â Â // Using the _.spread() method with its parameter var addition = _.spread(function(x, y) { Â Â return x + y; }); Â Â // Calling addition with its values addition([56, 44]); |
