// input.js `${ + 0 }` [ 0 ] = 0 ; // Note: this is fine // `${ 0 }` [ 0 ] = 0 ; _____________________ Hello, Executing the input.js using JSC throws SyntaxError, but it is expected to be terminated normally. This bug looks similar to the bugs I found: https://bugs.webkit.org/show_bug.cgi?id=247435 and https://bugs.webkit.org/show_bug.cgi?id=247497. However, I personally think this may not be a duplicate of Bug 247435 and Bug 247497, so please let me know if this bug is duplicated or not. Running the input.js with JSC results in: --- $ jsc input.js Exception: SyntaxError: Left hand side of operator '=' must be a reference. at input.js:1 --- while other engines behave like: --- # V8 $ node input.js // no error # GraalJS $ js input.js // no error --- WebKit version: 615.1.10
