Mysterious macro – Since it would make little sense to

Since it would make little sense to resolve variables before executing the surrounding JavaScript code, it follows that GTM does not resolve variables until a custom HTML tag is entered at the end of . The value of the variable must match the value of the entered custom HTML tag. When you create a custom HTML tag in Google Tag Manager, you are actually creating HTML elements that are added to the end of the element when the tag is triggered. Now, when a Google Tag Manager variable is added to a custom HTML tag, the syntax {{{variableName}} is used. In order for variables to wait for injection, this must mean that the variables themselves must be some sort of function call that will execute and resolve the surrounding script after the tag is injected. The main exception to this rule is variables converted to strings, which Google Tag Manager must resolve before injection, otherwise it will convert the function expression itself to a string, which is not appropriate.
