JavaScript, how to export multiple functions
How to export multiple functions from a JavaScript file
In JavaScript we can separate a program into separate files. How do we make the functions we define in a file available to other files?
You typically write a few functions, like this:
function sum(a, b) {
return a + b
}
function mul(a, b) {
return a * b
}
and you can make them available for any other file using this syntax:
export { sum, mul }
The files that need the functionality exported will import all the functions, or just the ones they need:
import { sum, mul } from 'myfile'
import { mul } from 'myfile'
