Implement function createTemplate which takes string with tags wrapped in {{brackets}}
as input and returns closure, which can fill string with data (flat object, where keys are tag names).

let personTmpl = createTemplate("{{name}} likes {{animalType}}");
personTmpl({ name: "John", animalType: "dogs" }); // John likes dogs

function createTemplate(template) {     
  
  return function(obj) {

    for (attr in obj) {      
      var pattern = new RegExp('{{' + attr + '}}', "g");      
      var matchText = pattern.test(template) ? obj[attr] : '' ;
      console.log(matchText);
      template = template.replace(pattern,matchText );             
    }        
    
    return template;
  }
}

var personTmpl = createTemplate("{{name}} likes {{animalType}}");
personTmpl({ names: "John", animalType: "dogs" }); // John likes dogs

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Finish the solution so that it returns the sum of all the multiples of 3 or 5 below the number passed in.

//an = a1 + (n - 1)d
//Sn = (n/2)(a1 + an)

function solution(number){  
    return getSum(3, number -1 ) + getSum(5, number- 1) + getSum(15, number- 1);
}
    
function getSum(difference,number) {  
  var frequency = Math.floor(number / difference);  
  var lastNumber = difference + (frequency - 1) * difference;
  return (frequency/ 2) * (difference + lastNumber);
}
