We can also use the += operator to concatenate a string onto the end of an existing string variable. This can be very helpful to break a long string over several lines.
Note
Watch out for spaces. Concatenation does not add spaces between concatenated strings, so you'll need to add them yourself.

Instructions

Build myStr over several lines by concatenating these two strings:
"This is the first sentence. " and "This is the second sentence." using the += operator.

Sollution:
// Example
var ourStr = "I come first. ";
ourStr += "I come second.";

// Only change code below this line

var myStr = "This is the first sentence. ";
myStr += "This is the second sentence.";

FreeCodeCamp.com - Basic JavaSript - Passing Values to Functions with Arguments

Link Parameters are variables that act as placeholders for the values that are to be input to a function when it is called. When a function is defined, it is typically defined along with one or more parameters. The actual values that are input (or "passed" ) into a function when it is called are known as arguments . Here is a function with two parameters, param1 and param2 : function testFun(param1, param2) { console.log(param1, param2); } Then we can call testFun : testFun("Hello", "World"); We have passed two arguments, "Hello" and "World" . Inside the function, param1 will equal "Hello" and param2 will equal "World". Note that you could call testFun again with different arguments and the parameters would take on the value of the new arguments. Instructions Create a function called functionWithArgs that accepts two arguments and outputs their sum to the dev console. Call the function...

FreeCodeCamp.com - Basic JavaSript - Word Blanks

Link to FreeCodeCamp We will now use our knowledge of strings to build a " Mad Libs " style word game we're calling "Word Blanks". You will create an (optionally humorous) "Fill in the Blanks" style sentence. You will need to use string operators to build a new string, result , using the provided variables: myNoun , myAdjective , myVerb , and myAdverb . You will also need to use additional strings, which will not change, and must be in between all of the provided words. The output should be a complete sentence. We have provided a framework for testing your results with different words. The tests will run your function with several different inputs to make sure all of the provided words appear in the output, as well as your extra strings. Sollution function wordBlanks(myNoun, myAdjective, myVerb, myAdverb) {   var result = "";   // Your code below this line   result+= "My "+myAdjective+" "+myNoun+...

FreeCodeCamp.com - Basic JavaSript - Understand String Immutability

Link to FreeCodeCamp In JavaScript, String values are immutable , which means that they cannot be altered once created. For example, the following code: var myStr = "Bob"; myStr[0] = "J"; cannot change the value of myStr to "Job", because the contents of myStr cannot be altered. Note that this does not mean that myStr cannot be changed, just that the individual characters of a string literal cannot be changed. The only way to change myStr would be to assign it with a new string, like this: var myStr = "Bob"; myStr = "Job"; Instructions Correct the assignment to myStr to achieve the desired effect. Sollution // Setup var myStr = "Jello World"; // Only change code below this line myStr = "Hello World";
