In the following example,
the output is displayed
based on the if condition -
number % 2 === 0.
We can also use the Ternary operator
to achieve the same logic
from the example given above.
The Ternary operator has
three parts or operands.
-
It starts with
a condition followed by
the ? operator.
-
It is then
followed by two expressions,
separated by the : operator.
-
The expression to the left
of the : operator is evaluated
when the condition is true.
-
The expression to the right
of the : operator is evaluated
when the condition is false.
In the following example,
the numberType variable is assigned
a value based on the result of a
ternary operation.
The numberType variable will be assigned
"even", i.e., the expression on
the left side of the : operator,
if the condition
number % 2 === 0 is true.
The numberType variable will be assigned
"odd", i.e., the expression on
the right side of the : operator,
if the condition
number % 2 === 0 is false.
The Ternary operator
requires fewer lines of code,
when compared to the
if...else statement,
making it easy to write.
The reduced lines of code also
make it easy to read and
comprehend the logic.
The Ternary operator
should only be used
when all three operands
are small.
Using the Ternary operator
with large operands
makes the code
less comprehensible
and
harder to debug
in the future.
