    Variable ERR_WRITER_SIZE_NOT_WRITABLEConst

    ERR_WRITER_SIZE_NOT_WRITABLE: string

    Invalid writer size error

    Thrown when WritableWriter#size cannot be assigned, e.g. when it is a getter with no setter, a read-only property or a frozen object. zip.js writes the number of bytes written into that property, so a writer refusing the assignment used to fail with a bare TypeError from the engine, and only once the first entry had been written.
