Save the result of a calculation to use afterwards - JS / JavaScript

Good night everyone, I have a problem and I have no idea how to solve it, I recently started a web course and the initial subject was JS. So that I could test my knowledge, thanks to the tip of a friend, I decided to create a "game" and managed to develop much of what I had in mind, however after doing the damage calculation after the actual attack of one of the characters and compiling the code again the HP of both of them returns to the default value. My question is how do I save the new HP of the characters to use again until it reaches zero?

Note: I accept other tips also so that I can improve my code / logic

constructor(Job, AP, MagicResist, PhisicalResist, Strengh, HP = 1000) {
    this.Job = Job; this.AP = AP; this.MagicResist = MagicResist; this.PhisicalResist = PhisicalResist; this.Strengh = Strengh, this.HP = HP
}
}

Status_Mage.Job = 'Mage'
Status_Mage.AP = 58
Status_Mage.MagicResist = 42
