Js Record Vs Object at Kevin Brent blog

Js Record Vs Object. Key differences between record and object in typescript. // for every properties k of type t, transform it to u. Object types are sets of objects containing at least all properties defined on this type, but they can also contain more. Understanding how to iterate over typescript record types is crucial for effectively accessing the data within these structures. In typescript, we call the way of accessing an object property with square brackets an index. The object type is meant to abstract away any keys of an object, whereas record<k, t> exists to specifically define the keys of a type. In this section, we will explore various methods to iterate over record types, including foreach, for.in, object.keys(), and object.values(). What makes it different or useful? Object types and records both represent sets of javascript objects. With the examples, we see how to derive record<> types by assigning types for keys and value, discuss how a record<> type is advantageous over simple object types and index signatures, and try to understand the quirks of its usage. Typescript 2.1 introduced the record type, describing it in an example:
