Lodash _.prototype.plant() Method
Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.
The _.prototype.plant(value) method of Sequence in lodash is used to create a clone of the chain sequence type by planting the value to be planted as the wrapped value.
Syntax:
_.prototype.plant(value)
Parameters: This method accepts single parameter as mentioned above and described below:
- value: It is the value that need to be planted.
Return Value: This method returns the new lodash wrapper instance.
Example 1:
Javascript
// Requiring lodash library const _ = require('lodash'); // Creating an addition function function add(n) { return n + n; } // Creating wrapped value var wrapper = _([4, 4]).map(add); // Calling prototype.plant(value) method var res = wrapper.plant([8, 8]); // Displays output console.log(res.value()); wrapper.value(); |
Output:
[ 16, 16 ] [ 8, 8 ]
Example 2:
Javascript
// Requiring lodash library const _ = require('lodash'); // Creating a function function fun(n) { return (n * 5); } // Calling prototype.plant(value) method var obj = _().map(fun).plant({'f': 5, 'g': 7}); // Displays output console.log(obj.value()); |
Output:
[ 25, 35 ]
Here, the values are multiplied by 5 and then returned as output.
