Lazy javascript template literals

lazy-template-literals.js

const templatized = (template, vars = {}) => {
  const handler = new Function('vars', [
    'const tagged = ( ' + Object.keys(vars).join(', ') + ' ) =>',
      '`' + template + '`',
    'return tagged(...Object.values(vars))'
  ].join('\n'))

  return handler(vars)
}


const templateString1 = 'Hello ${name}!'
console.log(templatized(templateString1, {
  name: 'world'
}))
// Hello world!

const templateString2 = 'Example with ${thing}.'
const thing = 'globals'
console.log(templatized(templateString2))
// Example with globals.

Many thanks for this, was looking for something to handle runtime creation of template literals (for different email templates, etc)
Normally use an object so have modified it slightly to:

const dynamicTemplate = (template, o) => {
  const handler = new Function( 'o', 'const tagged = (o) => `' + template + '`; return tagged(o)' )
  return handler(o)
}

then

const template1 = 'Hello ${o.name}!'
let o = {name: 'world'}
console.log(dynamicTemplate(template1, o ))
// Hello world!
