4 Approaches To Pass Arguments To JavaScript Functions
by Chris Jonathan

Approach 1: Positional Arguments: Direct Value Passing

  • Positional arguments involve passing values in the order expected by the function. It simplifies function calls but requires remembering the correct order, making it essential for understanding basic parameter passing in functions.

Approach 2: Keyword Arguments: Named Parameter Values

  • Keyword arguments allow passing values with corresponding parameter names. This provides clarity and flexibility in function calls, enabling developers to explicitly assign values to specific parameters, enhancing code readability and reducing errors in large functions.

Approach 3: Default Arguments: Setting Parameter Defaults

  • Default arguments involve setting default values for parameters. This ensures that if a value isn't provided, the function uses the default. It simplifies function calls and makes functions more versatile by handling different scenarios gracefully.

Approach 4: Rest Parameters: Handling Arbitrary Arguments

  • Rest parameters use the spread syntax (...) to pass an arbitrary number of arguments. This feature allows functions to handle varying input lengths, making them more dynamic. It's particularly useful when dealing with functions that can accept different numbers of arguments.
