- funcs: This parameter holds the functions that are to be invoked. It is an optional parameter.
Return Value:
This method returns the new composite function.
Example 1: In this example, we are using the _.flow() method and passing a function cube and the _.multiply() method and returning the result.
Javascript
// Requiring the lodash library const _ = require("lodash");// Function to calculate the// Cube of a numberfunction cube(number) { return number * number * number;}// Using the _.flow() method let multiplycube = _.flow([_.multiply, cube]);// Return the outputconsole.log(multiplycube(2, 3)); |
Output:
216
Example 2: In this example, we are using the _.flow() method and passing a function doubled and the _.add() method and returning the result.
Javascript
// Requiring the lodash library const _ = require("lodash");// Function to calculate the// double value of a numberfunction doubled(number) { return number * 2;}// Using the _.flow() method let adddoubled = _.flow([_.add, doubled]);// Return the outputconsole.log(adddoubled(6, 8)); |
Output:
