56533eb9ac21ba0edf2244b9	Constructing Strings with Variables	1	https://scrimba.com/c/cqk8rf4	16805

Description

Sometimes you will need to build a string, Mad Libs style. By using the concatenation operator (+), you can insert one or more variables into a string you're building.

Instructions

Set myName to a string equal to your name and build myStr with myName between the strings "My name is " and " and I am well!"

Tests

tests:
  - text: <code>myName</code> should be set to a string at least 3 characters long
    testString: assert(typeof myName !== 'undefined' && myName.length > 2);
  - text: Use two <code>+</code> operators to build <code>myStr</code> with <code>myName</code> inside it
    testString: assert(code.match(/["']\s*\+\s*myName\s*\+\s*["']/g).length > 0);

Challenge Seed

// Example
var ourName = "freeCodeCamp";
var ourStr = "Hello, our name is " + ourName + ", how are you?";

// Only change code below this line
var myName;
var myStr;

After Test

(function(){
  var output = [];
  if(typeof myName === 'string') {
    output.push('myName = "' + myName + '"');
  } else {
    output.push('myName is not a string');
  }
  if(typeof myStr === 'string') {
    output.push('myStr = "' + myStr + '"');
  } else {
    output.push('myStr is not a string');
  }
  return output.join('\n');
})();

Solution

var myName = "Bob";
var myStr = "My name is " + myName + " and I am well!";
