This is so even if the name is on a new line. ASI applies *only* if an offending token not allowed by the grammar is encountered, and there's no [no LineTerminator here] restriction in LexicalDeclaration or ForDeclaration forbidding a line break. It's a tricky point, but this is true *even if* the name is "let", a name that can't be bound by LexicalDeclaration or ForDeclaration. Per 5.3, static semantics early errors are validated *after* determining productions matching the source text. So in this testcase, the eval text matches LexicalDeclaration. No ASI occurs, because "let\nlet = ..." matches LexicalDeclaration before static semantics are considered. *Then* 13.3.1.1's static semantics for the LexicalDeclaration just chosen, per 5.3, are validated to recognize the Script as invalid. Thus the eval script can't be evaluated, and a SyntaxError is thrown. negative: phase: parse type: SyntaxError ---*/ $DONOTEVALUATE(); let // start of a LexicalDeclaration, *not* an ASI opportunity let = "irrelevant initializer";
