javascript remove characters from beginning of string

// this will replace the first occurrence of "www." and return "testwww.com"
"www.testwww.com".replace("www.", "");

// this will slice the first four characters and return "testwww.com"
"www.testwww.com".slice(4);

// this will replace the www. only if it is at the beginning
"www.testwww.com".replace(/^(www\.)/,"");

delate char betwen index js

// First find the substring of the string to replace, then replace the first occurrence of that string with the empty string.

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

//Another way is to convert the string to an array, splice out the unwanted part and convert to string again.

var result = S.split("");
result.splice(bindex, eindex - bindex);
S = result.join("");
