John Nunns
@johnnunns
so that would only match one word
and we need it to match all the words
JD Tadlock
@jdtdesigns
/(pickles)/g will match all the 'pickles'
Darth Skywalker
@adityaparab

@johnnunns

so that would only match one word

No. That will only match a string word

it won't match anything else.
John Nunns
@johnnunns
right sorry that's what I mean
so what regexp matches all the words together that match?
Darth Skywalker
@adityaparab
the right regex for that is \w or [A-Za-z]
the w in \w should be small
capital W like \W will match nonword characters
John Nunns
@johnnunns
var regex = new Regexp(\w, 'g')
JD Tadlock
@jdtdesigns
so to create an expression using the RegExp object, you would do it like this
var regex = new RegExp('(' + word + ')', 'g')
John Nunns
@johnnunns
aha...
JD Tadlock
@jdtdesigns
which outputs /(myword)/g
John Nunns
@johnnunns
what's the reason for ' ' around ()?
JD Tadlock
@jdtdesigns
you can't place the argument into the expression without string concatenation
otherwise it will just match the exact word you put in
that's the only reason you need to use the RegExp object
otherwise you could just use straight regex
John Nunns
@johnnunns
function countWords(str) {
    str.split(' ')
    .reduce(function(result, word){
        var regex = new Regexp( '(' + word + ')', 'g')

    },{})
    return result
}
fair enough!
JD Tadlock
@jdtdesigns
lookin good
but
John Nunns
@johnnunns
ok so now we need to set the counter
JD Tadlock
@jdtdesigns
result needs to be inide the callback
inside*
John Nunns
@johnnunns
so I don't need to return result outside?
JD Tadlock
@jdtdesigns
result refers to object you are building inside the callback
it needs to be returned inside
John Nunns
@johnnunns
I thought it automatically did that in reduce I guess..
alright so the counter. result[word] = regex something something something
JD Tadlock
@jdtdesigns
result[word] = ....
;)
you're building result lol
result starts as {}
and inside the callback you build it with each value in the array passed to it
so you split the string and reduce is iterating over each word
each word is passed to the callback
and you do something with the word and add it to the result object
John Nunns
@johnnunns
so the values that we want to put inside it is the regex amounts
regex.length?
JD Tadlock
@jdtdesigns
that's where .match() comes into play
you can use the regex you created to match the amount of those words ;)
John Nunns
@johnnunns
haha I thought we matched them already?
JD Tadlock
@jdtdesigns
the regex is just regex lol
it needs to be used somehow
John Nunns
@johnnunns
ok fair enough. so how about result[word] = str.match(regex)?
.length

@h1tag
How do you create html elements using jquery? I found multiple ways on google, not sure which one is right.
John Nunns
@johnnunns
it's definitely wrong after submitting haha, but a good try right
