I recently started learning Node.js and I want to know how to let a function accept multiple strings in the form of an array. For example,

export default (config: Config) => 
 return 
 target: 'https://google.com',
 endpoint: null,
 tick: 500,
 verbose: true,
 once: false,
 

So instead of target: "https://google.com", I'd like something like target: ['https://google.com', 'https://facebook.com']. There's probably something I'm missing but I'm a bit lost on how to do this.

You can use rest parameters. The syntax is

 const hello = (...args) => 
 // args is now an array
 console.log(args)
 

Then you can use it like so:

hello('This ', 'is ', 'an ', 'example') // outputs ['This ', 'is ', 'an ', 'example']

You can pass any number of arguments in it.

So back to your example, you could have some like

const example = (...targets) => 
 return 
 target: targets,
 endpoint: null,
 tick: 500,
 verbose: true,
 once: false,
 


module.exports = example

And you can use it like so

const example = require('./example')

let val = example('google', 'twitter', 'yahoo')
console.log(val)

Rest parameter should be the last parameter in your function. So if you want to pass some other params, the syntax is

function hello(param, ...rest) 
 // rest is an array
 ...

You could also directly pass an array or a variable referencing an array:

function hello(param) 
 ...
 console.log(param)


hello(["hello", "world"]) // outputs ["hello", "world"]
or
var arr = ["hello", "world"]
hello(arr)
