I was reading the article on Javascript Objects (/), so I copy-pasted the following code into my Notepad++ and ran it in Chrome(Version 55.0.2883.87 m). Upon opening the console, console reports SyntaxError. Does someone have an idea why? Everything seems ok.

// We have been using dot notation so far in the examples above, here is another example again:​
​var book = {title: "Ways to Go", pages: 280, bookMark1:"Page 20"};
​
​// To access the properties of the book object with dot notation, you do this:​
console.log(book.title); // Ways to Go​
console.log(book.pages); // 280

• You ran it where? In a browser (which one), in nodejs, in something else entirely? – UnholySheep Commented Dec 30, 2016 at 16:32
• 1 When I copied & paste your code to the console, I saw 2 invisible characters - That's the reason – Alon Eitan Commented Dec 30, 2016 at 16:34
• 1 Copy/paste can pick up invisible characters that will cause those errors. Just type the code in by hand. – Pointy Commented Dec 30, 2016 at 16:34
• var book = {title: "Ways to Go", pages: 280, bookMark1:"Page 20"}; console.log(book.title); console.log(book.pages); Should work (without the invisible characters) – Alon Eitan Commented Dec 30, 2016 at 16:35
• 1 Open developer tools (Ctrl+Shift+I) and copy the code in your question in the console tab. Hit the Enter key, and then hit the up arrow key, and you'll see in the code red dots – Alon Eitan Commented Dec 30, 2016 at 16:37

If you copy everything you just pasted and write it in the console, you would see that there are some unicode characters (\u200b) in your code which are actually the Invalid or unexpected token in the error that you are getting, you don't see them because they are zero-width spaced, so just remove them and the code would run perfectly as shown below

// We have been using dot notation so far in the examples above, here is another example again:
var book = {title: "Ways to Go", pages: 280, bookMark1:"Page 20"};

// To access the properties of the book object with dot notation, you do this:
console.log(book.title); // Ways to Go
console.log(book.pages); // 280
