semicolons

[Sonia]

Is a semicolon compulsory after each statement in JavaScript?
If no, why do we use semicolons in JavaScript statements at all?

Semi-colon are not necessary for the most part in javascript. Most of us probably use them out of habit. I'm also a PHP programmer, and forgetting a semi-colon in that will not be pretty...

[Sonia]

You said 'most part of JavaScript'. Therefore there are some places where it is compulsory?

[pyro]

Yes, take this example (two function calls in an onclick):

<a href="#" onclick="one() two() return false">test</a>

That will not work, we need to use:

<a href="#" onclick="one(); two(); return false">test</a>
