I'm new to Javascript and I'm try to understand some code. I don't understand and I can't find any documentation about the #
sign.
$(function () {
$("#searchTerm").autocomplete({
What does $("#searchTerm") mean?
Now # would/could mean private instance fields: https://tc39.github.io/proposal-class-fields/
2021 update:
Class fields are public by default, but private class members can be created by using a hash # prefix. The privacy encapsulation of these class features is enforced by JavaScript itself.
class ClassWithPrivateField {
#privateField;
}
class ClassWithPrivateMethod {
#privateMethod() {
return 'hello world';
}
}
class ClassWithPrivateStaticField {
static #PRIVATE_STATIC_FIELD;
}
class ClassWithPrivateStaticMethod {
static #privateStaticMethod() {
return 'hello world';
}
}

In JavaScript? Nothing special. It is just part of a string.
The $
function might do something with it, but it is hard to tell what the $
function is.
There are a lot of libraries which provide a $
function that acts as a kitchen sink for that library. They include Prototype, Mootools and jQuery. This one looks most like jQuery, in which case the argument is a string containing a CSS selector, so the #
indicates the start of an id selector.
This "Selects a single element with the given id attribute".
