Keep promises and build trust: the importance and value of promise

Promise is the cornerstone of building trust between people. A person who can keep his promises has reliable and trustworthy qualities and can establish good communication and cooperation with others. However, in real life, we often encounter violations of promises, which leads to the breakdown of trust, which not only affects the individual's image, but also has a negative impact on the team and society. Therefore, understanding and adhering to the importance and value of commitments is of great significance to personal growth and social development.

First of all, keeping promises is the basis for establishing trust between people. In interpersonal relationships, commitment is not only a verbal commitment, but also a kind of responsibility and respect for others. When we make a promise, the other person expects us to take action to fulfill our promise, and this behavior builds trust in us. Conversely, if we fail to deliver on our commitments, we undermine others' trust in us and may face rejection or ostracism from future collaborations. Therefore, keeping our promises means that we will be responsible for our own actions and increase the trust of others in us.

Secondly, keeping your promises is the key to building a good reputation. A person who can keep his promises usually has a good reputation and reputation. They are consistent in their words and deeds, keep their word and are able to win the respect and trust of others. For example, if a businessman can fulfill his commitments in accordance with the contract, customers will have a high degree of recognition of his credibility and be willing to cooperate with him for a long time. For another example, at work, if we can deliver results on time and fulfill our commitments, our leaders and colleagues will have a higher evaluation of our work attitude and professional ethics. Therefore, keeping promises helps to establish a good personal image and brand and establish a stable interpersonal network.

However, keeping promises is not easy. In real life, we often face various temptations and challenges, and it is easy to break promises. How to keep our promises is a question that each of us needs to face and think about. Here, I recommend a specific method and tool: the Promise library. Promise is a JavaScript library for handling asynchronous operations, which helps us better manage and fulfill promises.

The Promise library provides a more concise and controllable way to handle asynchronous logic by packaging asynchronous operations into Promise objects. Promise objects have three states: Pending (in progress), Fulfilled (successful) and Rejected (failed). When an asynchronous operation is completed, the Promise object can be changed from the Pending state to the Fulfilled or Rejected state by calling the Promise's resolve() method or reject() method. We can handle the state changes of the Promise object by registering callback functions for success and failure respectively through the .then() method and the .catch() method.

Use a specific example to illustrate the application scenarios and functions of Promise. Suppose we need to obtain the user's personal information through a network request, and then perform the next step based on the information. We can use the Promise library to handle this asynchronous operation.

First, we create a Promise object and write asynchronous logic in the constructor. We can use the XMLHttpRequest object to send network requests and process the returned data by listening to its onload event.

function getUserInfo() {
  return new Promise((resolve, reject) => {
    const xhr = new XMLHttpRequest();
    xhr.open('GET', 'http://api.example.com/user');
    xhr.onload = function() {
      if (xhr.status === 200) {
        resolve(xhr.responseText);
      } else {
        reject(xhr.statusText);
      }
    };
    xhr.onerror = function() {
      reject('Network Error');
    };
    xhr.send();
  });
}

Then, we can register success and failure callback functions respectively to handle the state changes of the Promise object.

getUserInfo()
  .then((response) => {
    console.log('Success: ', response);
    // 在这里根据返回的数据进行下一步操作
  })
  .catch((error) => {
    console.log('Error: ', error);
    // 在这里处理错误情况
  });

By using the Promise library, we can better manage and handle asynchronous operations and better keep promises. Whether it is success or failure, we can use the .then() method or the .catch() method to handle the corresponding situation, avoiding the callback hell and uncontrollable code structure that easily occur when using callback functions.

To sum up, keeping promises is the cornerstone of building trust and is a respectable and trustworthy quality. Through specific examples, we can see the application value of the Promise library in practice. Not only can it help us better handle asynchronous logic, but it can also remind us to stick to our commitments, stay true to our original aspirations, and improve our personal qualities. Everyone should understand and value the importance and value of commitment, and on this basis, establish a social environment of integrity and trust.
