Boolean Naming Convention
Boolean naming convention
Boolean, in programming, is a data type that is either true
or false
. Prefixes like is
, has
, and are
added in the booleans to distinguish them from other variables. Boolean data-type has two values true
or false
.
Note We will discuss booleans in more detail in the upcoming chapters.
// Not clear that the identifier is a boolean let clear = true; console.log(clear); // clear that the identifier is a boolean let isClear = true; console.log(isClear);
Swipe to start coding
Declare a boolean variable with an identifier Raining
. Use the prefix is
with the above boolean variable and store the false
value in it. Display the value of the variable in the end.
