The list of JavaScript conditional statements
STATEMENT CODE DESCRIPTION
the if statement IF ... ELSE IF ... ELSE This kind of statement controls the flow of the code execution based on the results of given comparison.
the switch statement SWITCH ... CASE ... DEFAULT This type of a conditional statement is always used for more than a few solutions needed in a regular code flow and therefore it is applied to more complex situations than the if statement.
the while statement WHILE The while statement is a loop executing kind of a statement used to pre-test flow code conditions.
the do-while statement DO ... WHILE The do...while statement is a loop executing kind of a statement used to post-test flow conditions. Due being a post-test statement, the loop gets executed at least one time.
the for statement FOR This type of a statement is the most popular loop execution statement. The reason for that is due to we can initialize variables, set the expression, and start the iteration in a single line of code.
the for-in statement FOR (property IN object) The for...in statement is used to return a property or properties of an object.
the break statement BREAK This statement works great with if statements and for loops. A break statement exits the loop immediately and the execution continues with the first line after the loop.
the continue statement CONTINUE This statement works great with if statements and for loops. A continue statement stops the loop immediately but it doesn't exit it, it actually continues from the top of the same loop; therefore it just skips the current loop count.
labels LABEL: The labels or label statements are often used with the loops in sense that they "tell" the loop where in code to jump to after a condition has been met.
the with statement WITH The with statement sets the scope of the code within a particular object.
