implementation of builder pattern in typescript

[vijayswarnkar21]

Hi,
implementation of builder pattern in TS looks like -

export class Student {
name: String;
age: Number;

constructor(studentBuilder: StudentBuilder) {
    this.name = studentBuilder.name;
    this.age = studentBuilder.age;
}

}

export class StudentBuilder {
private _name: String = "";
private _age: Number = 0;

constructor(){
    
}

setName(name: String) {
    this._name = name
    return this
}

setAge(age: Number) {
    this._age = age
    return this
}

get name(): String {
    return this._name
}

get age(): Number {
    return this._age
}

build() {
    return new Student(this);
}

}

==================================================
client code:
const student = new StudentBuilder().setName("vijay").setAge(29).build()

======================================================

but in java it is some what different.

or there is better way to implementing it.

Here object is not immutable
