Research direction
Start with the JavaScript grammar behavior for the reproduced < x and && 1 > 0 expression, then compare it with the numeric variant in the issue. Review the related #752 issue and the grammar files in this repository to identify the relevant rule. Done means both examples receive correct JavaScript syntax highlighting.
Written by the indexing model from the issue text.
Description
TS and JS Grammar Extension version: clicking previous link (in chrome 91.0.4472.114 on macos 10.13.6) gives 404 but searching vscode 1.59.1 extensions for @builtin typescript shows vscode.typescript-language-features 1.0.0 and vscode.typescript 1.0.0. Installing ms-vscode.vscode-typescript-next 4.5.20210902, found in this repo's readme, made no difference.
Code
vscode language mode: JavaScript
const x = 1;
0
< x
&& 1 > 0 // incorrect syntax highlight color coding
The issue seems to be that < x … > is interpreted as some type specification (like in array<int>)?
Compare with following where the last x is replaced with 1.
const x = 1;
0
< 1
&& 1 > 0 // correct syntax highlight color coding
I found #752 but decided to open a new issue.
