syntax for an if statement

[Help]

is this the correct syntax for an if statement?

if myVariable == 10{
alert("Your variable is equal to 10");}

[vickers_bits]

parenthesis

if (myVariable == 10){
alert("Your variable is equal to 10");}

If you are only executing one statement, you don't need the curly braces:
if (myVariable == 10) alert("Your variable is equal to 10");

And if the statement comes at the end of a line, then you do not need the semi-colon.

if (myVariable == 10) alert("Your variable is equal to 10")
