The article explains how the ??
operator offers a more precise way to assign default values compared to the traditional ||
operator.While ||
treats any falsy value (like 0
, false
, or ""
) as a trigger to apply the default, ??
only considers null
and undefined
as falsy.This distinction ensures that valid falsy values, such as 0
or false
, are not mistakenly replaced, leading to more predictable and reliable code.
