input script 190: for(let [let];;); input script 205: for(let [a, a];;) earlyErrors: false

Expected: No Exceptions Actual: Exception

` ../shift-parser-js/dist/parser.js:748 throw this.createError(_errors.ErrorMessages.UNINITIALIZED_BINDINGPATTERN_IN_FOR_INIT); ^

Error: [1:15]: Binding pattern appears without initializer in for statement init `

This is a misclassified test; shift-parser is correct.

@Shilpi3 It looks like script 205 is not what you've copied into this issue.
