/**
 * @fileoverview Implementation of sprintf-like, python-%-operator-like,
 * .NET-String.Format-like functionality. Uses JS string's replace method to
 * extract format specifiers and sends those specifiers to a handler function,
 * which then, based on conversion type part of the specifier, calls the
 * appropriate function to handle the specific conversion.
 * For specific functionality implemented, look at formatRe below, or look
 * at the tests.

/**
 * Performs sprintf-like conversion, i.e. puts the values in a template.
 * DO NOT use it instead of built-in conversions in simple cases such as
 * 'Cost: %.2f' as it would introduce unnecessary latency opposed to
 * 'Cost: ' + cost.toFixed(2).
 * @param {string} formatString Template string containing % specifiers.
 * @param {...(string|number|undefined)} var_args Values formatString is to
 *     be filled with.
 * @return {string} Formatted string.
