In Python, pass lets you write a placeholder that does nothing, like:
def my_func():
pass
Is there a similar JavaScript pass statement or notation to do nothing without affecting code flow?

Is there a similar JavaScript pass statement or notation to do nothing without affecting code flow?
In JavaScript, you can simply write an empty block or an empty function to represent “do nothing”:
function myFunc() {
// do nothing
}
or
if (condition) {
// empty block acts like pass
}
It’s the closest equivalent to Python’s pass.
If you need a statement that does nothing on its own line, just use a semicolon:
if (condition)
;
It acts as a no-operation statement in JavaScript, similar to pass.
Sometimes, for placeholders, you can use an arrow function that returns undefined explicitly, which effectively does nothing:
const noop = () => {};
Use noop()
wherever you need a no-op callback or placeholder function. This is common in event handlers or promises.
