I am trying to make sense of this line of code:

const loanPeriod: number = get(product, 'TermMonths', this.defaultTerm) / this.monthsInAYear;

defaultTerm and monthsInAYear are global variables. product is an object and TermMonths is a number property of product. I don't know why the product & 'TermMonths' is needed. Can't you just divide the defaultTerm by monthsInAYear?

You can find the official documentation here, with an example. Using your case, the assumption is that product may or may not have a property called TermMonths. If it does, _.get will retrieve the value of that property. If it does not, the default, this.defaultTerm, is returned.
