在typescript中优化字符串生成器

const name = "John";
const age = 30;
const email = "john@example.com";

const userInfo = `Name: ${name}, Age: ${age}, Email: ${email}`;
console.log(userInfo);

const numbers = Array.from({ length: 100 }, (_, i) => (i + 1).toString());
const result = numbers.join(", ");
console.log(result);

class StringBuilder {
  private buffer: string[];

  constructor() {
    this.buffer = [];
  }

  append(str: string): void {
    this.buffer.push(str);
  }

  toString(): string {
    return this.buffer.join("");
  }
}

const sb = new StringBuilder();
sb.append("Hello");
sb.append(", ");
sb.append("World");
const result = sb.toString();
console.log(result);
