I need to replace a string by range
Example:

result = that is a string;

but this need to be dinamically. Cant be replace a fixed word ...need be by range

I have tried

           result = string.replaceAt(0, 'that');

but this replace only the first character and I want the first to third

function replaceRange(s, start, end, substitute) {

    return s.substring(0, start) + substitute + s.substring(end);

}



var str = this is a string;

var newString = replaceRange(str, 0, 4, that); // that is a string
