ES6 / ECMA6 template literals - not working
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}
Answers:
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) - 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: ${categoryElements} `)
Output:
VM626:1 categoryName: name
categoryElements: element
See: What is the usage of the backtick symbol (`) in JavaScript?
1.) add .jshitrc same folder level with your app.js and other files
2.) put this inside the newly created file { "esversion": 6 }
3.) never use single quote ' use backticks `
// Example
var person = {
name: "Meera",
hello: function(things) {
console.log(`${this.name} Says hello ${things}`);
}
}
// Calling function hello
person.hello("World");
//Meera Says hello Worldyou need to use `` instead of single ' ' or double quotes " " . these quotes will be found in the button on the left of number 1.
Happy coding !!
