Quizplus · Accepted Answer

The toLocaleString() method can format numbers as currency and also separate thousands with a comma symbol. It provides more control over the numeric format than the toFixed() method. The other options are not suitable for formatting numbers as currency. Currency code is simply the symbol or code used to represent a currency, useGroup: Boolean is a property used for specifying whether grouping should be used when displaying numbers, and element.oninput is an event handler used for triggering an action when the user inputs data into an HTML element.
