This might help you That's the inline script. When you use javascript in html you use javascript:your_method() or simply yourmethod()
code :
<a href="javascript:history.go(-1)">click</a>

With these it helps Your snippet of code looks like it's referencing methods from one of the popular JavaScript libraries (jQuery, ProtoType, mooTools, and so on).
There's nothing mysterious about the use of $ in JavaScript. $ is simply a valid JavaScript identifier.

To fix the issue you can do It's not supposed to be javascript but a template file. Template file contains static html and very dumb presentation logic, usually in a pseudolanguage as it is in this case. It should not contain any real javascript - as it is said in the book that it's something you shouldn't do.
The book then goes into a refactored version that only has static html and the pseudolanguage statement. See Javascript templating.

I hope this helps . This is basically a sneaky way of coercing the right-hand operand into a numeric value. E.g.,
code :
> +"42"
42

it fixes the issue Pragmatically, it's JavaScript shorthand for converting a value to a Number. Technically, it's the unary plus operator, complementary to the unary negation operator.
code :
let number = "1"

console.log(typeof number)

console.log(typeof +number)
console.log(+number)

console.log(typeof -number)
console.log(-number)

console.log(typeof +true)
console.log(+true)
