An iterator over the lines of an instance of `BufRead`.

The at() method of TypedArray instances takes an integer value and returns the item at that index, allowing for positive and negative integers. Negative integers count back from the last item in the typed array. This method has the same algorithm as Array.prototype.at().

The findLastIndex() method of TypedArray instances iterates the typed array in reverse order and returns the index of the first element that satisfies the provided testing function. If no elements satisfy the testing function, -1 is returned. This method has the same algorithm as Array.prototype.findLastIndex().

The join() method of TypedArray instances creates and returns a new string by concatenating all of the elements in this typed array, separated by commas or a specified separator string. If the typed array has only one item, then that item will be returned without using the separator. This method has the same algorithm as Array.prototype.join().

The setBigInt64() method of DataView instances takes a BigInt and stores it as a 64-bit signed integer in the 8 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The getInt32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit signed integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

An iterator that filters the elements of `iter` with `predicate`.

The toLocaleString() method of BigInt values returns a string with a language-sensitive representation of this BigInt. In implementations with Intl.NumberFormat API support, this method delegates to Intl.NumberFormat.
