Bonfire-Convert-HTML-Entities.md

Problem Explanation:

• You have to create a program that will convert HTML entities from string to their corresponding HTML entities. There are only a few so you can use different methods.

Hint: 1

• You can use regular Expressions however I didn't in this case.

Hint: 2

• You will benefit form a chart with all the html entities so you know which ones are the right ones to put.

Hint: 3

• You should separate the string and work with each character to convert the right ones and then join everything back up.

Spoiler Alert!

Solution ahead!

Code Solution:

function convert(str) {
  // Split by character to avoid problems.

  var temp = str.split('');

  // Since we are only checking for a few HTML elements I used a switch

  for (var i = 0; i < temp.length; i++) {
    switch (temp[i]) {
      case '<':
        temp[i] = '&lt;';
        break;
      case '&':
        temp[i] = '&amp;';
        break;
      case '>':
        temp[i] = '&gt;';
        break;
      case '"':
        temp[i] = '&quot;';
        break;
      case "'":
        temp[i] = '&apos;';
        break;
    }
  }

  temp = temp.join('');
  return temp;
}

##Another Solution

function convert(str) {
    
    //map of key:value pairs
    var html = {
       "&":"&",
       "<":"&lt;",
       ">":"&gt;",
       "\"":"&quot;",
       "\'":"&apos;"
    };
        str = str.replace(/&|<|>|"|'/gi, function(matched){
        return html[matched];
        });

  return str;
}

##Another Solution

function convert(str) {
//Chaining of replace method with different arguments
  str = str.replace(/&/g,'&amp;').replace(/</g,'&lt;').replace(/>/g,'&gt;').replace(/"/g,'&quot;').replace(/'/g,'&apos;');
return str;
}
