@jdtdesigns yikes man trying to find the regex match words in mdn and not finding anything only character matches
JD Tadlock
@jdtdesigns
@johnnunns It's very easy to match words
/(myWord)/g would be the regex
John Nunns
@johnnunns
haha why isn't that the first thing I see after searching regex match words?
JD Tadlock
@jdtdesigns
this is a good one for .match()
i just typed 'match a word regex' to test and it's the first response lol
@johnnunns
John Nunns
@johnnunns
no way!
haha
google?
JD Tadlock
@jdtdesigns
yep
John Nunns
@johnnunns
/\b($word)\b/i
does that one work?
JD Tadlock
@jdtdesigns
/(word)/g
easy
John Nunns
@johnnunns
function countWords(str) {
    str.split(' ')
    .reduce(function(result, word){
        var regex = new Regexp(/word/g)

    },{})
    return result
how are we looking? @jdtdesigns
JD Tadlock
@jdtdesigns
@johnnunns That won't work because the regex will only match the word 'word' ;)
you need to create the expression using a string and concat the word into it
new RegExp('expression', 'options')
options would just be 'g' for this one
John Nunns
@johnnunns
g is global?
JD Tadlock
@jdtdesigns
and you don't need the two '/' in the expression string
yes
John Nunns
@johnnunns
I'm really not sure JD I only put /word/g in there because you said haha
JD Tadlock
@jdtdesigns
/(word)/g is the expression to match 'word'
Darth Skywalker
@adityaparab

@johnnunns

g is global?

g is global as in it will match all occurances. Otherwise, Reg Ex only matches first occurance.

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
