sum.sh

node // Here REPL open, I want copy below codes to this REPL and run

var num1 = 1
var num2 = 2
var sum = num1 + num2
sum

After run sum.sh, expecting result

Can we have a solution?

JavaScript does not run in the terminal. To run JavaScript in a Node.js file, you would install Node.js, create the script, and then run it from the terminal.

First, create the Node.js file which we'll call sum.js:

let num1 = 1;
let num2 = 2;
let sum = num1 + num2;
console.log(sum);

To run this file from the terminal we would type node sum.js.

To run this from a script, simply create a script, sum.sh with executable permissions to have the following: node sum.js

It's the same thing as running it from the terminal, but now it's in a script file.

You can't directly copy paste command into NodeJS REPL. I think you should try this one.

run command node and then running on REPL cli as follows .load sum.sh.

This would be run line by line as expected.

Reference. How do I load my script into the node.js REPL?
