The Invocation () Operator
Example
console.log(); // Invokes the log function
myFunction(); // Calls myFunction
Definition
When placed after a function name, () is the Invocation (Function Call) operator.
It executes the function and holds any arguments being passed to it.
Not Always Invocation
Parentheses are also used in other parts of the JavaScript syntax (not only function invocation):
- Expression grouping:
(x + y) * y - Wrapping if conditions:
if (age > 18) - Controlling loops:
for (let i = 0; i < 10; i++)
Browser Support
() is an ECMAScript1 (JavaScript 1997) feature.
