Below example illustrate the Lodash _.after() method in JavaScript.
Example 1: In this example we try to invoke the function 3 times but it will in invoke 3rd times only.
// Requiring the lodash library const _ = require("lodash"); // Applying _.after() method var gfg = _.after(3, function () { console.log('Saved'); }); gfg(); // Print nothing gfg(); // Print nothing gfg(); // Print Saved |
Output:
Saved
Example 2: In this example we try to invoke the function 2 times but it will in invoke 2nd times only.
// Requiring the lodash library const _ = require("lodash"); // Applying _.after() method var gfg = _.after(2, function () { console.log('Successful'); }); gfg(); // Print nothing gfg(); // Print Successful |
