Is assigning a variable to a function a form of calling a function?

The IsFieldEmpty function is not called explicitly or assigning fieldTest to this function part of the process?

" function isFieldEmpty () { const field = document.querySelector ('#info'); if (field.value === '') { return true; } else { return false; } }

const fieldTest = isFieldEmpty();

if (fieldTest === true) { alert('You need to provide info'); }"

This isn't "assigning a variable to a function", it is assigning a variable with the value returned from a function.

But yes, the function gets called to get the value to assign to the variable.

Thanks for the clarification. are there any other ways to call a function besides using "function ();" and assigning a variable to a function?
