substituteswith

Substituteswith is a term used in programming, data processing, and templating to describe an operation that replaces occurrences of a given value, pattern, or placeholder with another value. The phrase is not a standardized keyword in any single language, but appears as a function or method name in various libraries and frameworks, with spellings such as substitutesWith or substitutes_with.

In string processing, substituteswith typically takes at least two arguments: the target to replace and the replacement value. It may also accept options such as global replacement (all occurrences versus the first), case sensitivity, and escaping rules. In data transformation, substituteswith can operate on elements of a collection, substituting according to a mapping or predicate. Some implementations support conditional substitution, where a value is swapped only if another condition holds, and might allow complex patterns or regular expressions as targets.

Semantics of substituteswith can vary: it may be pure, returning a new value without altering the original input, or it may perform in-place modification in languages that allow mutable data. It can also be used in a partially applied form, creating a function that applies a fixed replacement to any input. This flexibility makes substituteswith a common concept in template engines, data pipelines, and functional utilities, even though its exact behavior is library-dependent.

See also: replace, substitute, mapping, templating, pattern matching. Note that substituteswith is not a universal standard term; its meaning is defined by the library or language in which it appears.
