string matching in javascript / regex -

what best way match 2 strings contain same phrase? example there way match following 2 strings:

st1 = 'jenissplendidicecreams' st2 = 'jenisicecream' 

what proper regex match 2 strings?

you need build regexp looks this:

/.*j.*e.*n.*i.*s.*i.*c.*e.*c.*r.*e.*a.*m.*/ 

this regexp matches if string being tested includes original characters, in order, arbitrary additional characters in between.

we can build enough doing

function make_regexp(str) {     var letters = str.split('');     letters.push(''), letters.unshift('');     return new regexp(letters.join('.*')); }  > make_regexp('jenisicecream') < /.*j.*e.*n.*i.*s.*i.*c.*e.*c.*r.*e.*a.*m.*/ 

now test if second string matches:

> make_regexp('jenisicecream').test('jenissplendidicecreams') < true
