IIFE. TypeError: require(…)(…) is not a function

Question

Running simple script. Got an error.

const fetch = require(\"node-fetch\")
const url = \"https://www.someurl.com\"

(async ()=>{
    con         


        

Answer 1

Automatic Semicolon Insertion(ASI) doesn't work as you expect it to in some cases.

IIFEs fall into one of those cases, where the parentheses are concatenated with previous line code.

To ameliorate this, just prefix your IIFE's with a semicolon:

const fetch = require("node-fetch")
const url = "https://www.someurl.com"

;(async () => {
    const response = await fetch(url)
    console.log(response)
})()

Or as @estus suggests in the comments, just avoid writing semicolon-less code.
