如何从Angular中的JSON类型数据中删除花括号{}和双引号"“？

let jsonData = { "name": "John", "age": 30 };
let jsonString = JSON.stringify(jsonData);
let modifiedString = jsonString.replace(/[{}"]/g, '');

console.log(modifiedString);

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'removeBracesQuotes'
})
export class RemoveBracesQuotesPipe implements PipeTransform {
  transform(value: any): any {
    let jsonString = JSON.stringify(value);
    let modifiedString = jsonString.replace(/[{}"]/g, '');
    return modifiedString;
  }
}

<p>{{ jsonData | removeBracesQuotes }}</p>
