Assuming the string is called myStr      Strip start and end quotation mark and possible initial comma myStr myStr replace            replace               Split stripping quotations myArray myStr split           Note that if a string can be missing in the list without even having its quotation marks present and you want an empty spot in the corresponding location in the array  you ll need to write the splitting manually for a robust solution

You can use directly replace function on javascript with regex or define a help function as in php ltrim left  and rtrim right    1  With replace   var myArray      first string   more   even more   replace    s        split             2  Help functions   if   String prototype ltrim  String prototype ltrim   function         return this replace    s            if   String prototype rtrim  String prototype rtrim   function         return this replace   s             var myArray      first string   more   even more   ltrim   split          filter function el   return el length    0       You can do and other things to add parameter to the help function with what you want to replace the char  etc

var s      first string   more   even more      s split          filter function v    return v        Results in       first string    more    even more      First split with commas possibly surrounded by single quotes  then filter the non-truthy  empty  parts out

To turn a string into an array I usually use split     gt  var s      first string   more   even more    gt  s split            first string    more    even more      This is almost what you want  Now you just have to strip the first two and the last character    gt  s slice 2  s length-1   first string   more   even more    gt  s slice 2  s length-2  split           first string    more    even more     To extract a substring from a string I usually use slice   but substr   and substring   also do the job

To remove the first character you would use   var myOriginalString      first string   more   even more     var myString   myOriginalString substring 1     I m not sure this will be the result you re looking for though because you will still need to split it to create an array with it  Maybe something like   var myString   myOriginalString substring 1   var myArray   myString split         Keep in mind  the   character will be a part of each string in the split here

In this specific case  there is always a single character at the start you want to remove  you ll want   str substring 1    However  if you want to be able to detect if the comma is there and remove it if it is  then something like   if  str 0               str   str substring 1
