Import and Export Javascript Functions/Files
// Let us assume that this is the file you are working with and you need some arithmetic functions
//below is the import statement
const math = require("math.js")
let num1 = 10
let num2 = 20
console.log(math.add(num1,num2)) //math.add is how we will be accessing the add functions from the math.js file
make sure that you pass two arguments, since add function requires two arguments.
