Like all computer languages, JavaScript has certain
advantages and disadvantages. Many of the pros and cons are
related to being a client-side language.
Advantages of JavaScript
* Speed. Being client-side, JavaScript is very fast
because any code functions can be run immediately instead of
having to contact the server and wait for an answer.
* Simplicity. JavaScript is relatively simple to learn
and implement.
* Versatility. JavaScript plays nicely with other
languages and can be used in a huge variety of applications.
Unlike PHP or SSI scripts, JavaScript can be inserted into
any web page regardless of the file extension. JavaScript
can also be used inside scripts written in other languages
such as Perl and PHP.
* Server Load. Being client-side reduces the demand on
the website server.
Disadvantages of JavaScript
* Security. Because the code executes on the users'
computer, in some cases it can be exploited for malicious
purposes. This is one reason some people choose to disable
JavaScript.
* Reliance on End User. JavaScript is sometimes
interpreted differently by different browsers. Whereas
server-side scripts will always produce the same output,
client-side scripts can be a little unpredictable. Don't be
overly concerned by this though - as long as you test your
script in all the major browsers you should be safe.
