The ToString() technique of this object just calls String.Structure(structure, values). But there is also an overload that accepts an IFormatProvider, and this is where points get attention-grabbing, because it causes it to be attainable to personalize how the values are formatted.

Flag is real In constrained scenarios you may want to use two-way binding, and you'll specify it by including the ngModel directive being an HTML attribute surrounded with both equally parentheses and sq. brackets, for example:
