using two strings as object parameter js code example

Example 1: javascript string concat vs +

It is strongly recommended to use the string
concatenationoperators (+, +=) instead of String.concat
method for perfomance reasons

const author = "Pablo Neruda";

const favePoem = `My favorite poem is ${poem} by ${author}.`;
