Usage

import { Interpreter, SliceParser } from 'tagscript';
const ts = new Interpreter(new SliceParser());

const { Interpreter, SliceParser } = require('tagscript');
const ts = new Interpreter(new SliceParser());

Notes

Start index is inclusive, end index is exclusive
Negative indices count from the end of the string
If only start index is provided, slices from that position to the end
Uses JavaScript's String.slice() method internally
