how can i remove chars between indexes in a javascript string

Question

i have the following:

var S=\"hi how are you\";
var bindex = 2;
var eindex = 6;

how can i remove all the chars from S that reside between

Answer 1

You can:

1. get the substring from bindex and eindex
2. remove spaces from that string

3. rebuild the string

   var new_s = S.slice(1, bindex) + S.slice(bindex, eindex).replace(/\s/g, '') + S.slice(eindex)
