JS Pass-by-Reference

main.js

// Now pass-by-reference
let c = { language: "Javascript" }
let d = c

console.log(c) // => {language: "Javascript"}
console.log(d) // => {language: "Javascript"}

// Let's mutate our object 'd'
d.language = "Ruby"

console.log(c) // => {language: "Ruby"}
console.log(d) // => {language: "Ruby"}

// Meaning mutating the object d also mutates the object c - Because 'd' points to the same reference-location as 'c' .
