Argument
Arguments are values (primitive or object) passed as input to a function. Do not confuse arguments with parameters, which are the names used in the function definition to refer to the arguments.
For example:
js
const argument1 = "Web";
const argument2 = "Development";
example(argument1, argument2); // passing two arguments
// This function takes two values
function example(parameter1, parameter2) {
console.log(parameter1); // Output = "Web"
console.log(parameter2); // Output = "Development"
}
The argument order within the function call should be the same as the parameters order in the function definition.
js
const argument1 = "foo";
const argument2 = [1, 2, 3];
example(argument1, argument2); // passing two arguments
// This function takes a single value, so the second argument passed is ignored
function example(parameter) {
console.log(parameter); // Output = foo
}
