javscript hello code example

Example 1: javascript hello world

I would do something like this:

<script>
  alert("Hello World!");
</script>

Example 2: js hello world

let thisIstheSourceObjectforOurhelloWorldCode = {character1:"h",character2:"e",character3:"l",character4:"l",character5:"o",character6:"SPACE",character7:"w",character8:"o",character9:"r",character10:"l",character11:"d"}
