How to return a string starting from specified character? Javascript

Question

I have to create a function that searches for the first occurrence of the character c (an unsigned char) in the string pointed to by the argument str. The terminating null character is considered to be part of the string.

So i did this:

function my_strchr(str, c){
return str.substring(c.length + str.indexOf(c));
}

But it returns a string without c character. For example, input is "abcabc" && b. Expected output is bcabc, but I have cabc. Could anybody help?

Answer 1

make it like this and it should be okay

return str.substring(str.indexOf(c));

it will start from the index of C till the end of str
