updateRow

updateRow is a common operation in data manipulation libraries and APIs used to modify the contents of a single row in a tabular data structure. The function typically targets a row by an identifier, such as a numeric index or a unique key, and applies new values to one or more fields. Most implementations take two main inputs: the row identifier and a map or object of field-value pairs to set. Depending on the library, updateRow may replace the entire row or update only the specified fields, leaving others unchanged.

In memory and persistence behavior vary by context. Some implementations update data in memory and require a separate save or commit operation to persist changes, while others perform an atomic update against a backing store and persist immediately. Return values are also context dependent: a successful call may return the updated row, a boolean success flag, or a promise/future in asynchronous environments. On failure, methods may throw an exception or return an error object.

Contexts and examples. In relational databases, similar results are achieved with an UPDATE statement that targets a row by a key and sets new values. In client-side data grids or spreadsheet-like libraries, updateRow often triggers validations, events, or re-rendering of the affected row. Some systems support partial updates, validation hooks, or automatic conflict resolution in concurrent environments.
