To make code easy to read and maintain, we should follow some best practices.

In this article, we’ll look at some best practices we should follow to make everyone’s lives easier.

Named Function Expressions

Names in function expressions aren’t very useful.

If we set the function to a variable, we can’t use it with that name.

We also don’t need it much in IIFEs.

So we can write:

Foo.prototype.bar = function() {};

instead of:

Foo.prototype.bar = function bar() {};

Also, we can write:

(function() {
    // ...
}())

instead of:

(function bar() {
    // ...
}())

Unless we need the name inside the function, it’s not that useful.
