Functions can have multiple parameters:
function add(a, b) {
console.log(a + b)
}
add(5, 3) // 8
add(10, 20) // 30
function introduce(name, age, city) {
console.log(`${name}, ${age}, from ${city}`)
}
introduce("Alice", 30, "Seattle")
Parameters are matched by position. The first argument goes to the first parameter, second to second, and so on.
