How to import a JavaScript function from a JavaScript file in the same directory?

This below is my index.js, the file where i'm trying to call an imported function

const mysyn = require('./syntax.js')
router.post("/",(req,res)=>
{
var code = (req.body.Code);
console.log(syn(code));
res.send("POST") 
}
);

and this is syntax.js:

const syn = function(code)
{
   console.log("In sep html"+ code );
}
module.exports = syn;

I tried using ES6 import statement but that didn't work since node throws back the 'Unexpected token {' error. So, How do I come across this?

Your importing and exporting seems to be correct.

Just change this

console.log(syn(code));

To this

console.log(mysyn(code));

In order to import a function, you have to export the function.

in syntax.js, you need to export the function like this:

module.exports = syn

And in your index.js file you have to assign the exported function into a local variable like this:

const mySynFn = require('./syntax.js');
