single or double quotes!

Hey Monique!

Could you share what error you're getting from using double quotes with "sun". Just curious as there shouldn't be any error as far as I know.

As for the "console.log" statements needing to use double quotes for their string literals. It all comes down to the fact that the strings contain apostrophes in words like "I'm", and "It's". Due to the fact that the apostrophe and the single quote share the same key, you must use double quotes otherwise the javascript engine will believe that the string ends at the apostrophe. This will likely causing errors as it tries to figure out what everything else means.

What happens when using 'single quotes':

console.log('I do not know if I'm going to the supermarket today') 

 // In the example above, the javascript engine only recognizes:
 // 'I do not know if I' as the entire string. (Highlighted in orange)

Additionally, since the string is concluded at the single quote in the word "I'm", the single quote at the end, after the word today, marks the beginning of a new string literal that doesn't have an end. This is something that will likely cause javascript to throw an error.

What happens when using "double quotes":

console.log("I do not know if I'm going to the supermarket today.")

 // In this example above, the javascript engine recognizes: 
 // "I do not know if I'm going to the supermarket today" as the entire string (Highlighted in orange)

Same thing can happen when trying to use multiple double quotes

console.log("I would like to "Jimmy" to step up to the plate.")

 // In the example above, the javascript engine recognizes:
 // "I would like to " and " to step up to the plate." as two separate strings. (Highlighted in orange)

In this example the word "Jimmy" isn't included in the string and will likely throw up an error as it's unexpected in the syntax.

What happens when using 'single quotes'

console.log('I would like "Jimmy" to step up to the plate')

 // In this example above, the javascript engine recognizes: 
 // 'I would like "Jimmy" to step up to the plate' as the entire string (Highlighted in orange)

Doing it this way would yield the intended result.

Using an escape character

If you decided you really want to use all single quote for a string that contains apostrophes, or double quotes within a string literal created with double quotes. You do have the option of using an escape character before the the respective quote mark.

console.log('I do not know if I\'m going to the supermarket today.') 

// javascript will recognize this as:
// 'I do not know if I'm going to the supermarket today' not displaying showing the backslash.

console.log("I would like to \"Jimmy\" to step up to the plate.")

// javascript will recognize this as:
// "I would like to "Jimmy" to step up to the plate." not displaying showing the backslashes.

Adding the backslash () allows the ' or the " to be used within the string. However, without ending the string literal.
