- start: It is the start position of the spread. It is an optional parameter. The default value is 0.
Return Value:

Example 1: In this example, we are passing two strings in a function and printing the result in the console by the use of the lodash _.spread() method.
// Requiring lodash library
const _ = require('lodash');
// Using the _.spread() method with its parameter
let write = _.spread(function (author, portal) {
return author + ' writes for ' + portal + '!';
});
// Calling write with its values
console.log(write(['Nidhi', 'GeeksforGeeks']));
Output:
Nidhi writes for GeeksforGeeks!Example 2: In this example, we are passing two numbers in a addition function and printing the result in the console by the use of the lodash _.spread() method.
// Requiring lodash library
const _ = require('lodash');
// Using the _.spread() method with its parameter
let addition = _.spread(function (x, y) {
return x + y;
});
// Calling addition with its values
console.log(addition([56, 44]));
Output:
