Description
TS Template added by @mjbvz
TypeScript Version: 4.0.0-dev.20200708
Search Terms
- javascript
- lib.dom
- globals
- VSCode Version: 1.46.1
- OS Version: Windows 10
Steps to Reproduce:
- Add the following javascript code
var name = "Hi";
console.log(name);
name = "Hello";
console.log(name);
-
Hover over(Mouseover) the variable "name" (in any of the console log statements given above).......picture attached.
-
Expected: During mouse/hover over, variable "name" on the console statement should display "name" as a variable.
Actual: During mouse/hover over, variable "name" on the console statement is showing it as constant. (actually, it's not a constant). Because I'm able to modify the value of the variable "name" from "Hi" to "Hello". This explains "name" is implemented as a variable.

No source file or test is named in the report.

Done means the hover for the reassigned name is identified as a variable rather than a constant.
