alter.js

Alters a string by replacing multiple range fragments in one fast pass. Works in node and browsers.

Usage

    var alter = require("alter");
    alter("0123456789", [
        {start: 1, end: 3, str: "first"},
        {start: 5, end: 9, str: "second"},
    ]); // => "0first34second9"

The fragments does not need to be sorted but must not overlap. More examples in test/alter-tests.js
