This is my original TypeScript code. let printOutput = (fahrenheit: number, celsius: number) => { console.log(`${fahrenheit}f = ${celsius}c.`); }; let convert = (fahrenheit: number) => { let celsius = ((fahrenheit - 32) * (5 / 9)); return celsius; }; let fahrenheit = 100; let celsius = convert(fahrenheit); printOutput(fahrenheit, celsius); Returns. ...

I was struggling to get some code working in JavaScript and realised that I’d made a small variable type error. This is one of the problems in working with a loosely typed language like JavaScript.
