Keyboard and Mouse interactions with and without build() method of Actions class

In order to perform mouse and keyboard actions, Selenium WebDriver has Actions class. Suppose if we want to double click an element, we'll have code like following -

Actions builder=new Actions(driver);
builder.doubleClick(visibleElement).build().perform();

Same we can have without build() method like -

builder.doubleClick(visibleElement).perform()

For both, I saw same behaviour. Could you please help to understand how it impacts actions with and without build() method.

In existing tests, suppose I've actions without build() and now I use it or I have tests with build() and now I remove it, how will it affect test execution behaviour?
