Can you make sure that this code is evaluated properly, and add a test? let length = 1;
"abc"[length]; |
|
@nicolo-ribaudo I've fixed that case. |
|
The Jest integration test failed due to some changes on the Jest side. I submitted #15319 to fix those issues; I merged the commit from that PR into this one to make sure there are no other issues with the build. |
This allows expressions like "hello world"[6] to be evaluated.
