TSAssignmentStatement

A class that represents a TypeScript assignment statement in a codebase, such as const x = 1 or const { a: b } = myFunc(). This includes potentially multiple Assignments via statement.assignments, which represent each assignment of a value to a variable within this statement. For example, assigning to a destructured object, or assigning multiple values to multiple variables in a single statement.
