But what if you want to match the word 'null'?

[Biohazard000Labs]

@JakleIsMe word.match(null); ?

[JakleIsMe]

@Biohazard000Labs But then how would you be able to tell if it found it or not, since it would display null either way?

Thank you Bucky,all your vedio is great

[ramlah20023]

amazing !

what is his website ?

[gf133]

the example of validation seems highly unnatural - nobody is going to validate by trying to predict misspellings users might make

a quick mention of simple regular expressions would make it much more enlightening what the point of match is

[petepetefok]

You are a very very good teacher.

I'm not sure. He kind of slurs a bit.

But I do know that the link on the side does not match any of the sounds he makes.

I've been wondering: is there any difference between double and single quotes?

I use single most of the time, unless there's an apostrophe in the given string, because that screws everything up and I need to switch to double.

But then if my string has a quoted piece of text in it that causes a problem with double quotes and I have to switch back to single.

But if I had a string with an apostrophe AND quoted text I guess I would be screwed. Any way around this?

[FeedMEBabies]

i think you put \ [backslash] before the ' or " if you wish to put them into the string.

[Wowccraft]

such as alert('Don\'t touch that!')

[patrick99e99]

This is no difference between using double or single quotes.

As far as your problem goes, there are two solutions:

1) use html ascii codes instead of the single/double quote. In other words var x = 'it's hot today'.

or var x = "she said "Don't talk back!&quot";

2) use a backslash to escape the quotes. var x = 'it\'s hot in here!';

or var x= "she said \"Don't talk back!\"";

The programming parts are going to be so fun. Hopefully it will teach us to include sound and images.
