Excellent work! In this lesson, we’ve learned the following concepts:
- An
if
statement consists of a condition and code block that executes when the condition istrue
. - An
else
statement is immediately followed by a code block that executes when all previous conditions werefalse
. - A code block is denoted by a set of curly braces
{}
. - Multiple
else if
statements can be chained within anif
/else
to provide additional conditions. - Comparison operators include
<
,>
,<=
,>=
,==
, and!=
and are used to compare the values of two operands. - A
switch
statement looks for the value of a case that matches the value of an expression. - A
switch
statement can have cases that contain multiple items known as compound cases. - A
switch
statement’s case can include a range of values using the closed range operator (...
).
