how can i remove chars between indexes in a javascript string -

-

i have following: 

var s="hi how you"; var bindex = 2; var eindex = 6;

how can remove chars s reside between bindex , eindex?
therefore s "hi you"

first find substring of string replace, replace first occurrence of string empty string.

s = s.replace(s.substring(bindex, eindex), "");

another way convert string array, splice out unwanted part , convert string again.

var result = s.split(''); result.splice(bindex, eindex - bindex); s = result.join('');
