The _.debounce() method 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.
