error handling

[Gaute945]

add error handling for every command

Rationale

this would minimize the ammount of error

Implementation Details

Try-Catch Blocks: Use try and catch blocks to encapsulate code that might throw an error. If an error occurs within the try block, the control is transferred to the catch block where you can handle the error.

try {
  // Code that might throw an error
} catch (error) {
  // Handle the error
  console.error(error.message);
}

Throwing Errors: Use the throw statement to explicitly generate an error. You can throw predefined errors or create custom ones.

function divide(a, b) {
  if (b === 0) {
    throw new Error("Cannot divide by zero");
  }
  return a / b;
}

Async/Await Error Handling: When using async/await, use try-catch blocks to handle errors.

async function fetchData() {
  try {
    let data = await fetchDataFromAPI();
    console.log(data);
  } catch (error) {
    console.error("Error fetching data:", error.message);
  }
}

Event Emitters and Callbacks: For handling errors in asynchronous operations like callbacks or events, check for errors in the callback function.

const fs = require("fs");

fs.readFile("example.txt", "utf8", (err, data) => {
  if (err) {
    console.error("Error reading file:", err.message);
    return;
  }
  console.log(data);
});
