# Lodash Debounce

The _[.debounce() method](https://dev.to/lamhoanghg/lodash-debounce-24kl) of Function in lodash is used to create a debounced function that delays the given function until after the stated wait time in milliseconds has passed since the last time this debounced function was called. The debounced function has a cancel method that can be used to cancel the function calls that are delayed and a flush method that is used to immediately call the delayed function. 

**Syntax:**

`_.debounce( func, wait, options )`

**Parameters:** This method accepts three parameters as mentioned above and described below:

- **func**: It is the function that has to be debounced.
- **wait**: It is the number of milliseconds for which the calls are to be delayed. It is an optional parameter. The default value is 0.
- **options**: It is the options object that can be used for changing the behaviour of the method. It is an optional parameter.

The options object has the following parameters:

- **leading**: It defines the calling on the leading edge of the timeout. It is an optional parameter. The default value is false.
- **maxWait**: It is the maximum number of time for which the func is allowed to be delayed before it is called. It is an optional parameter.
- **trailing**: It defines the calling on the trailing edge of the timeout. It is an optional parameter. The default value is true.


```
// Requiring lodash library
const _ = require('lodash');
  
// Using _.debounce() method
// with its parameters
var debounce_fun = _.debounce(function() {
  console.log('Function debounced after 1000ms!');
  }, 4, 1000, {'leading': false});
  
// Defining loop
var loop = function() {
    setTimeout(loop, 3)
    debounce_fun();
};
  
// Calling loop to start
loop();
```
