Why is this an issue?
Consistent naming between arguments and parameters reduces the chances of making mistakes, such as passing the wrong value to a parameter or
omitting an argument in a function call. When the names of arguments in a function call match the names of the function parameters, it contributes to
clearer, more readable code.
However, when the names match but are passed in a different order than their declaration in the function signature, it may indicate a mistake in
the parameter order, likely leading to unexpected results.
function divide(dividend, divisor) {
return dividend / divisor;
}
function doTheThing() {
const dividend = 15;
const divisor = 5;
const result = divide(divisor, dividend); // Noncompliant: not the expected result
//...
}
Ensure that the arguments passed to the function are in the correct order, according to the function signature.
function divide(dividend, divisor) {
return dividend / divisor;
}
function doTheThing() {
const dividend = 15;
const divisor = 5;
const result = divide(dividend, divisor);
//...
}
Exceptions
Swapped arguments that are compared beforehand in an enclosing if
statement are ignored:
function divide(dividend, divisor) {
return dividend / divisor;
}
function doTheThing() {
const dividend = 5;
const divisor = 15;
if (divisor > dividend) {
const result = divide(divisor, dividend);
//...
}
}
