Learn how to define and access local variables in a template.
- [Instructor] Local template variables…allow you to reference and access HTML elements…and their associated properties…within other HTML elements in the view.…Now, defining a local variable is simple.…You use the hash sign and the name of the variable.…Then, depending on where you want to use that variable,…you use interpolation with the local variable name inside.…So, let's give it a try.…We can attach a local variable to any HTML element.…So, let's go ahead and get rid of…all of our current template.…
Here, we'll do an h1 and we'll define a local variable…with the hash sign myH1 inside,…my title and then we can also reference it…with a <p> tag here through interpolation, my H1.…So, let's save and go to our browser.…Now, we can see this local variable is an object.…
