eval() as it can pose security risks and lead to potential vulnerabilities in your code if used improperly. It can execute any arbitrary code provided as a string, which can include malicious or unintended commands.
Here’s an example of how
eval() can be used:
const code = "console.log('Hello, world!');"; eval(code);
In the above code, the
eval() function is called with the
eval() function executes the code and produces the expected output.
While this example demonstrates the basic usage of
eval(), it’s crucial to consider potential security risks. If the content of the
code string is dynamically generated or comes from an untrusted source (e.g., user input or external data), executing it with
eval() can introduce severe vulnerabilities, such as code injection attacks.
Instead of using
JSON.parse() to safely parse and work with the data.
