Question

class Students{
Students (name){
this.name=name;
}
}
var student1= new Students("Omega");
document.write("name"+student1.name);

Answer 1

i think javascript use "constructor" keyword

Answer 2

class Student {
constructor(studentName) {
this.studentName = studentName;
}
sayHi() {
return `${this.studentName} says hello & happy SoloLearning!`;
}
}
const student = new Student(`jsStudent`);
console.log(`${student.sayHi()}`);
The function called 'constructor' MUST be named that way (since that is what is run when the 'new' keyword is used).

Answer 3

Well, I suggest you to take JavaScript course first.
