How do I put variables inside javascript strings?

Question

s = \'hello %s, how are you doing\' % (my_name)

That\'s how you do it in python. How can you do that in javascript/node.js?

Answer 1

const format = (...args) => args.shift().replace(/%([jsd])/g, x => x === '%j' ? JSON.stringify(args.shift()) : args.shift())

const name = 'Csaba'
const formatted = format('Hi %s, today is %s and your data is %j', name, Date(), {data: {country: 'Hungary', city: 'Budapest'}})

console.log(formatted)
