COPY

Elements with the contenteditable attribute can be live-edited right in the browser window. But of course those changes don’t affect the actual document on your server, so those changes don’t persist with a page refresh. One way to save the data would be to wait for the return key to be pressed, which triggers then sends the new innerHTML of the element as an Ajax call and blurs the element. Pressing escape returns the element to it’s pre-edited state.

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
