Here's the FAQ on the private syntax: https://github.com/tc39/proposal-class-fields/blob/master/PR...
class fish {
color = "blue"; // color is now a name in scope for this class definition
#agenda = "Total World Domination" // agenda is now a name in scope for this class definition
...
reveal () {
console.log("I am a "
+ color + " Fish " // interpreted as this.color
+"seeking " + agenda // interpreted as this.#agenda;
}
}
class fish {
color = "blue";
private agenda = "World Peace"
constructor(){
color="red"
agenda="Secret World Domination"
}
reveal () {
console.log(`I am a ${color} Fish seeking ${agenda}`)
}
}
