The Importance of Using “use strict”; in SuiteScript

In the realm of SuiteScript, ensuring code quality and preventing common pitfalls is crucial for developing robust and maintainable applications. One effective way to achieve this is by using the "use strict"; directive. This article explores the benefits of incorporating "use strict"; in your SuiteScript code.

What is "use strict";?

"use strict"; is a directive introduced in ECMAScript 5 (ES5) that enables strict mode in JavaScript. When placed at the beginning of a script or a function, it enforces a stricter parsing and error handling of JavaScript code. This helps developers write cleaner, more secure, and less error-prone code.

Benefits of Using "use strict"; in SuiteScript

1. Enhanced Error Detection: Strict mode catches common coding mistakes and throws errors for unsafe actions. For example, it prevents the use of undeclared variables, which can lead to unexpected behaviors and bugs.
2. Improved Security: By disallowing certain potentially dangerous features, such as the use of with statements, strict mode helps enhance the security of your code. This reduces the risk of vulnerabilities and makes your SuiteScript applications more secure.
3. Cleaner Code: Strict mode enforces better coding practices by disallowing duplicate parameter names and octal literals. This results in cleaner, more readable code that is easier to maintain and debug.
4. Performance Optimization: Some JavaScript engines can optimize strict mode code better than non-strict mode code. This can lead to improved performance of your SuiteScript applications.
5. Future-Proofing: Using strict mode ensures that your code adheres to modern JavaScript standards. This makes it easier to transition to newer versions of JavaScript and maintain compatibility with future updates.

How to Use "use strict"; in SuiteScript

To enable strict mode in your SuiteScript code, simply add the "use strict"; directive at the beginning of your script or function:

/**
 * @NApiVersion 2.x
 * @NScriptType UserEventScript
 */
define(['N/record'], function(record) {
    "use strict";


    function afterSubmit(context) {
        // Your code here
    }


    return {
        afterSubmit: afterSubmit
    };
});

By incorporating "use strict"; in your SuiteScript code, you can take advantage of these benefits and develop more robust, secure, and maintainable applications.

Using "use strict"; in SuiteScript is a best practice that helps catch common errors, improve security, and ensure cleaner code. By enabling strict mode, you can enhance the quality and performance of your SuiteScript applications, making them more reliable and easier to maintain.
