Static & Private Class Fields

What benefit does private implementation provide for this data structure?

class Tree {
  #value;
  #left;
  #right;
  
  constructor(value) {
    this.#value = value;
  }
  
  insert(value) {
    if (value < this.#value) {
      if (this.#left) this.#left.insert(value);
      else this.#left = new Tree(value);
    } else {
      if (this.#right) this.#right.insert(value);
      else this.#right = new Tree(value);
    }
  }
}

Faster operations
Memory optimization
Protected internal structure
Private implementation protects the tree structure: 1) Node values cannot be directly modified, 2) Tree links cannot be tampered with, 3) Structure modification only through controlled methods, 4) Maintains data structure integrity, 5) Prevents invalid tree states, 6) Ensures proper tree operations.
