run eval in javascript

To run eval in JavaScript, you simply write eval followed by the JavaScript code you want to execute as a string. Here's an example:

index.tsx
let result = eval("2 + 2");
console.log(result); // Output: 4
62 chars
3 lines

In the above example, the eval function evaluates the string "2 + 2", which is a valid JavaScript expression. The evaluated result is then assigned to the variable result and subsequently logged to the console.

However, it's important to note that using eval can be dangerous and should be used with caution. Since it executes any code passed to it as a string, it presents a security risk if the input is not carefully validated. It is generally recommended to find alternative approaches whenever possible to avoid potential security vulnerabilities.
