Export in files

 two commands

require(file path) in the receiver

module.exports in the sender

in the export file

module.exports=123;

in the inport file

let val=require("./export");

console.log(val);

objects can be sent as

export

const sum=(a,b)=>a+b;

const mul=(a,b)=>a*b;

const g=9.8;

const pi=3.14;

let obj={

    mul:mul,

    sum:sum,

    g:g,

    pi:pi

}

module.exports=obj;

inport

let val=require("./export");

console.log(val.g);

console.log(val.pi);

console.log(val.sum(2,3));

console.log(val.mul(4,5));

they can also be sent as

module.exports={

    mul:mul,

    sum:sum,

    g:g,

    pi:pi

}

OR

module.exports.sum=(a,b)=> a+b;

module.exports.mul=(a,b)=> a*b;

module.exports.g=9.8;

module.exports.pi=3.14;

OR

exports.sum=(a,b)=> a+b;

exports.mul=(a,b)=> a*b;

exports.g=9.8;

exports.pi=3.14;
