TIL 23/04/21(module.exports)

relationship between module.exports and exports
when the module is called, it is just implicit(암묵적인) code

//module.exports = {}
let module ={exports : {}}
let exports = module.exports//just address of module.exports 

exports = 10 
//reassignment is broken the relationship with module.exports
exportx.x = 10 // add the x value in reperence(module.exports)

The same module is called only once.
