Can String Parameters in setTimeout Ever Be Practical?

Passing Strings to setTimeout: Is It Ever Justified?

The practice of passing a string to the setTimeout or setInterval functions is universally condemned in the development community. Concerns range from its execution within the global scope to potential performance and security implications. Instead, it's strongly recommended to encapsulate the code within an anonymous function.

However, a question arises: does the deprecated string syntax ever have any practical use?

The only plausible scenario seems to be accessing global functions or variables that have been overridden within a local scope. Even this situation is considered poor programming practice.

An alternative solution exists for utilizing global variables: access them through the window object, e.g., window.globalVar. This eliminates the need for the deprecated syntax.

Historically, the string-based syntax allowed limited functionality. The ability to pass a function object reference was introduced later. To avoid breaking existing code, browsers continue to support the use of strings. However, it's important to note that this syntax is outdated and should be avoided in modern programming practices.
