What is the difference between 'interface' and 'type' when defining object types?
Description : 'interface' supports merging; 'type' supports more complex types.
Answer :
'interface' and 'type' can both be used to define object types, but they have differences.'interface' allows declaration merging, meaning multiple 'interface' declarations with the same name are merged into one.'type', on the other hand, does not support merging but can define complex types like unions and intersections. Use 'interface'for extending and merging types and 'type'for more complex type definitions.
TypeScript is a statically typed language that builds on JavaScript by adding optional types. It allows developers to catch errors at compile time rather than runtime, which can help improve code quality and readability. TypeScript code is transpiled to JavaScript, making it compatible with existing JavaScript codebases and environments.
