 * A BasicSourceMapConsumer instance represents a parsed source map which we can

 * following attributes:
 *
 *   - version: Which version of the source map spec this map is following.
 *   - sources: An array of URLs to the original source files.
 *   - names: An array of identifiers which can be referrenced by individual mappings.
 *   - sourceRoot: Optional. The URL root from which all sources are relative.
 *   - sourcesContent: Optional. An array of contents of the original source files.
 *   - mappings: A string of base64 VLQs which contain the actual mappings.
 *   - file: Optional. The generated file this source map is associated with.
 *
 * Here is an example source map, taken from the source map spec[0]:
 *

/**
 * A regular expression for matching CSS import statements
 *
 * According to https://developer.mozilla.org/en-US/docs/Web/CSS/@import
 * the formal grammar for CSS import statements is:
 *
 * ```
 * @import [ <url> | <string> ]
 *     [ supports( [ <supports-condition> | <declaration> ] ) ]?
 *     <media-query-list>? ;
 * ```
 *
 * Thus the string literal `"@import"` will be followed by a `<url>` or a
 * `<string>`, where a `<url>` may be a relative or absolute URL _or_ a `url()`
 * function.
 *
 * Thus the regular expression needs to match:
 *
 * - the string `"@import
 * - any amount of whitespace
 * - a URL, comprised of:
 *   - an optional `url(` function opener
 *   - a non-greedy match on any characters (to match the argument to the URL
 *   function)
 *   - an optional `)` closing paren on the `url()` function
 * - trailing characters after the URL, given by anything which doesn't match
 *   the line-terminator `;`
 *   - this can match media queries, support conditions, and so on
 * - a line-terminating semicolon
 *
 * The regex has 4 capture groups:
 *
 * 1. `@import`
 * 2. `url(`
 * 3. characters after `url(`
 * 4. all characters other than `;`, greedily matching
 *
 * We typically only care about group 4 here.

// The assignment of fine-grained, information-carrying type objects
// allows the tokenizer to store the information it has about a
// token in a way that is very cheap for the parser to look up.

// All token type variables start with an underscore, to make them
// easy to recognize.

// The `beforeExpr` property is used to disambiguate between regular
// expressions and divisions. It is set on all token types that can
// be followed by an expression (thus, a slash after them would be a
// regular expression).
//
// The `startsExpr` property is used to check if the token ends a
// `yield` expression. It is set on all token types that either can
// directly start an expression (like a quotation mark) or can
// continue an expression (like the body of a string).
//
// `isLoop` marks a keyword as starting a loop, which is important
// to know when parsing a label, in order to allow or disallow
// continue jumps to that label.

// The following three functions all verify that a node is an lvalue —

//
// - Check that none of the bound/assigned-to identifiers are reserved words.
// - Record name declarations for bindings in the appropriate scope.
// - Check duplicate argument names, if checkClashes is set.
//
// If a complex binding pattern is encountered (e.g., object and array
// destructuring), the entire pattern is recursively checked.
//
// There are three versions of checkLVal*() appropriate for different
// circumstances:
//
// - checkLValSimple() shall be used if the syntactic construct supports
//   nothing other than identifiers and member expressions. Parenthesized
//   expressions are also correctly handled. This is generally appropriate for
//   constructs for which the spec says
//
//   > It is a Syntax Error if AssignmentTargetType of [the production] is not
//   > simple.
//
//   It is also appropriate for checking if an identifier is valid and not
//   defined elsewhere, like import declarations or function/class identifiers.
//
//   Examples where this is used include:
//   a += …;
//   import a from '…';
//   where a is the node to be checked.
//
// - checkLValPattern() shall be used if the syntactic construct supports
//   anything checkLValSimple() supports, as well as object and array
//   destructuring patterns. This is generally appropriate for constructs for
//   which the spec says
//
//   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
//   > an ArrayLiteral and AssignmentTargetType of [the production] is not
//   > simple.
//
//   Examples where this is used include:
//   (a = …);
//   const a = …;
//   try { … } catch (a) { … }
//   where a is the node to be checked.
//
// - checkLValInnerPattern() shall be used if the syntactic construct supports
//   anything checkLValPattern() supports, as well as default assignment
//   patterns, rest elements, and other constructs that may appear within an
//   object or array destructuring pattern.
//
//   As a special case, function parameters also use checkLValInnerPattern(),
//   as they also support defaults and rest constructs.
//
// These functions deliberately support both assignment and binding constructs,
// as the logic for both is exceedingly similar. If the node is the target of
// an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
// should be set to the appropriate BIND_* constant, like BIND_VAR or
// BIND_LEXICAL.
//
// If the function is called with a non-BIND_NONE bindingType, then
// additionally a checkClashes object may be specified to allow checking for
// duplicate argument names. checkClashes is ignored if the provided construct
// is an assignment (i.e., bindingType is BIND_NONE).

  <h1>This Stencil app is disabled for this browser.</h1>

  <h2>Developers:</h2>
  <ul>
  <li>ES5 builds are disabled <strong>during development</strong> to take advantage of 2x faster build times.</li>
  <li>Please see the example below or our <a href="https://stenciljs.com/docs/stencil-config" target="_blank" rel="noopener noreferrer">config docs</a> if you would like to develop on a browser that does not fully support ES2017 and custom elements.</li>
  <li>Note that as of Stencil v2, ES5 builds and polyfills are <strong>disabled</strong> during production builds. You can enable these <a href="https://stenciljs.com/docs/config#buildes5" target="_blank" rel="noopener noreferrer">in your stencil.config.ts file</a>.</li>
  <li>When testing browsers it is recommended to always test in production mode, and ES5 builds should always be enabled during production builds.</li>
  <li><em>This is only an experiment and if it slows down app development then we will revert this and enable ES5 builds during dev.</em></li>
  </ul>


  <h2>Enabling ES5 builds during development:</h2>
  <pre>
  <code>npm run dev --es5</code>
  </pre>
  <p>For stencil-component-starter, use:</p>
  <pre>
  <code>npm start --es5</code>
  </pre>


  <h2>Enabling full production builds during development:</h2>
  <pre>
  <code>npm run dev --prod</code>
  </pre>
  <p>For stencil-component-starter, use:</p>
  <pre>
  <code>npm start --prod</code>

  <h1>Update src/index.html</h1>

  <p>Stencil recently changed how scripts are loaded in order to improve performance.</p>

  <h2>BEFORE:</h2>
  <p>Previously, a single script was included that handled loading the correct JavaScript based on browser support.</p>
  <pre>
  <code>${escapeHtml(`<script src="/build/${config.fsNamespace}.js"></script>
`)}</code>
  </pre>

  <h2 style="margin-top:0">AFTER:</h2>
  <p>The index.html should now include two scripts using the modern ES Module script pattern.
  Note that only one file will actually be requested and loaded based on the browser's native support for ES Modules.
