ECMAScript template literals like 'some ${string}' are not working

Question

I wanted to try using template literals and it’s not working: it’s displaying the literal variable names, instead of the values. I am using Chrome v50.0.2 (and jQuery).

Example

console.log('categoryName: ${this.categoryName}\ncategoryElements: ${this.categoryElements} '); 

Output

${this.categoryName} categoryElements: ${this.categoryElements}

JavaScript template literals require backticks, not straight quotation marks.

You need to use backticks (otherwise known as "grave accents" - which you'll find next to the 1 key if you're using a QWERTY keyboard) - rather than single quotes - to create a template literal.

Backticks are common in many programming languages but may be new to JavaScript developers.

Example:

categoryName="name"; categoryElements="element"; console.log(`categoryName: ${this.categoryName}\ncategoryElements: ${categoryElements} `)  

Output:

VM626:1 categoryName: name  categoryElements: element
