d934401265 Change the type of 'uriComponent' (passed to 'encodeURIComponent') from 'string' to 'string | number | boolean'. Fixes #18159 (#31103) 
- According to the ECMAScript 5.1 spec (§15.1.3.4), 'encodeURIComponent' invokes the abstract operation 'ToString': https://www.ecma-international.org/ecma-262/5.1/#sec-15.1.3.4
- In the spec (§9.8), 'ToString' accepts an 'Undefined', 'Null', 'Boolean', 'Number', 'String' or 'Object' argument: https://www.ecma-international.org/ecma-262/5.1/#sec-9.8
- TypeScript’s 'StringConstructor' accepts an argument with type 'any': b0100100a1/lib/lib.es5.d.ts (L518)

f9d12ed54b fix 31012 allow noEmitOnError with isolatedModules (#34) (#31043) 
fix #31012

Since the purpose of isolatedModules: true is to
do extra validation to ensure that separate
compilation is safe

Allowing emit in the presence of errors is
compatible with that intention.

6487d1ffe0 Remove the rule that replaces a union of literal types with the base type when comparing equality to a type that isn't a union of literal types. (#27588) 
type when comparing equality to a type that isn't a union of literal
types.

The rule is redundant because a primitive type is already directed-
comparable to a value of that primitive type, and it causes errors to be
missed when comparing a type parameter _constrained_ by a union of
literal types to another union of literal types.

The baseline changes look like improvements to me.

Fixes #26758.

Handle JSDoc backticks in the parser, not scanner (#30939) 
* Scan backticks in jsdoc as a single token less often

Previously, matching backticks in jsdoc would always be scanned as one
token to aid parsing incorrect jsdoc that uses backticks for parameter
names:

``js
/** @param {string} `nope`
 * @param {number} `not needed`
 */
```

However, this is wrong for code fences, which use triple backticks. This
fix parses a single backtick as a single token if it's immediately
followed by another backtick or by a newline. It retains the
questionable tokenisation of backticks-as-pairs in other cases, however.
A better fix might be to have the parser ignore backticks in jsdoc
instead.

* Add test case

* Handle jsdoc backticks in the parser, not scanner

Previously, the jsdoc scanner had ad-hoc handling of backticks that was
similar in structure to the normal scanner's handling, but much simpler.
This was a smaller code change, but is handled backwards: the special
case of backtick-quoted parameter names was handled in the scanner
instead of in the jsdoc identifier parsing code. That made it overapply
and block correct handling of asterisks across newlines, which was most
obvious in code fences inside jsdoc, as in #23517.

Fixes #23517

* More cleanup
