What is the difference between type and enum?

Question

typescript

What is the difference between writing

type Weekdays = "mon" | "tue" | "wed" | "thur" | "fri" | "sat" | "sun";

and

enum Weekdays {  "mon",  "tue",  "wed",  "thur",  "fri",  "sat",  "sun" }

Well, except that enum will compile to JS - an object, and type will only be available at compile time.

Answer 1

The fact that . If exactly lines are needed in enum, then exactly lines should be specified: Otherwise, this:Weekday2s.mon === 0enum Weekdays { mon = "mon", ...}

Well, except that enum will compile to JS - an object, and type will only be available at compile time.

more than enough. Instead of working with strings (new each time), you work with an object.
