Introduction to GoLang
Conditional Chaining
We can use the else if
keyword to define an additional condition that will be evaluated in case the previous condition is not met:
index.go
In the above program, the expression 3 > 4
is checked first, which is false
; hence the program proceeds to the next statement (3 > 2
) defined using the else if
keyword. The next condition is true
, so the output displays the result of the second Println
statement.
We can add as many additional conditions as needed using else if
statements:
index.go
It's important to note that the above program only outputs 3 is greater than 2
, even though the next condition is also true
. This demonstrates that an if-else if
chain stops evaluating conditions as soon as it encounters a true
condition.
This process is referred to as conditional chaining because we are essentially defining conditions in a chain using if
-else if
keywords.
Note
In a conditional chain, only one code block is executed, the one that satisfies the condition, while the rest are skipped.
Alternatively, instead of chaining conditionals using the if
-else if
combination, we can write each condition using separate if
statements. However, this approach produces a different output because it's no longer a single chain; it's a set of separate conditions, and therefore, it won't stop executing if one or more of the conditions are met:
index.go
Up to this point, for the sake of simplicity, we have been using values in boolean expressions. However, it is more common to use variables or a combination of variables and values in boolean expressions:
index.go
In a conditional chain, we can use the else
keyword to indicate a code block that should be executed if none of the conditions in the chain are met:
index.go
