Temperature Converter

A temperature widget needs two conversion helpers and one formatting helper. Keep the math separate from the display text so each function has one clear job.

Write these functions:

• celsiusToFahrenheit(celsius) should convert Celsius to Fahrenheit and return the number.

• fahrenheitToCelsius(fahrenheit) should convert Fahrenheit to Celsius and return the number.

• formatTemperature(value, unit) should return display text such as "77 F" or "20 C".

Sample checks:

const fahrenheit = celsiusToFahrenheit(25);console.log(formatTemperature(fahrenheit, 'F'));const celsius = fahrenheitToCelsius(68);console.log(formatTemperature(celsius, 'C'));const freezingFahrenheit = celsiusToFahrenheit(0);console.log(formatTemperature(freezingFahrenheit, 'F'));const freezingCelsius = fahrenheitToCelsius(32);console.log(formatTemperature(freezingCelsius, 'C'));

Expected output:

77 F20 C32 F0 C

The conversion functions should return numbers. formatTemperature should return the final string.
