JavaScript Function Argument Limits
JavaScript allows functions to accept a flexible number of arguments, raising the question of whether this flexibility extends to arbitrary limits.
Theoretical Maximum
The ECMAScript specification does not explicitly restrict the number of arguments a function can have. As such, there is no theoretical maximum.
Practical Considerations
Despite the lack of theoretical constraints, in practice, JavaScript functions face limits imposed by browser implementations.
Implementation-Dependent Limits
The maximum number of arguments a function can accept varies across implementations, as evidenced by experiments conducted in a recent article.
For example:
Impact of Invocation Method
The method used to invoke a function can also affect the maximum number of arguments. Using the eval() method, for instance, often results in lower limits compared to other methods.
Conclusion
While there is no inherent limit on the number of arguments a JavaScript function can accept, practical constraints imposed by browser implementations typically restrict the number of arguments to a range between tens of thousands and millions. The actual limit depends on the specific implementation and the method of invocation.
