elementsFrom

elementsfrom is a programming concept used to describe an operation that yields a subset of elements from a source collection starting at a specified point. The exact form and semantics of elementsfrom vary across languages and libraries, but the core idea is to produce a view or new sequence containing elements from a chosen starting position onward. Variants such as elementsFrom or elements-from appear in documentation and APIs, reflecting different naming conventions.

Common usage patterns include starting from a fixed index, such as elementsfrom(collection, index), which returns the elements from that index to the end. Another pattern uses a predicate or condition, where elementsfrom(collection, predicate) begins at the first element that satisfies the condition and continues to the end. In streaming or lazy contexts, elementsfrom may produce a lazy view that references the original data source without copying, enabling efficient processing of large or infinite sequences.

Examples illustrate the idea without relying on a specific language syntax. elementsfrom([1, 2, 3, 4, 5], 2) would yield [3, 4, 5] in a positional variant. elementsfrom([1, 2, 3, 4], x => x >= 3) would yield [3, 4] in a predicate-based variant. For streams, a method like stream.elementsfrom(index) could produce the remaining events starting at the given point.

Notes and caveats: behavior can differ when the starting point is absent or out of range, and the return type may be a new collection or a view. Always consult the specific language or library documentation for exact semantics. See also: slicing, sublists, drop, take, and windowing.
