Are curly braces necessary in one line statements in JavaScript?
I am almost positive of this, but I want to make sure to avoid faulty code. In JavaScript do single if statements need curly braces?
if(foo) bar; Is this OK?

If the true or false clause of an if statement has only one statement, you do not need to use braces (also called "curly brackets"). This braceless style is dangerous, and most style guides recommend always using them.
You can have as many else if statements as necessary. In the case of many else if statements, the switch statement might be preferred for readability. As an example of multiple else if statements, we can create a grading app that will output a letter grade based on a score out of 100.
In C# curly braces are optional, but only for the first line of code. Meaning that if the statement does not have braces, only the line of code right after the if condition (the statement body) will be executed. Everything else falls outside the statement body and therefore will not be executed.
Yes, it works, but only up to a single line just after an 'if' or 'else' statement. If multiple lines are required to be used then curly braces are necessary.
The following will work
if(foo) Dance with me; else Sing with me; The following will NOT work the way you want it to work.
if(foo) Dance with me; Sing with me; else Sing with me; You don't know anything; But if the above is corrected as in the below given way, then it works for you:
if(foo){ Dance with me; Sing with me; }else{ Sing with me; You don't know anything; } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
