eslint/prefer-template Style

🛠️ An auto-fix is available for this rule.

Require template literals instead of string concatenation.

In ES2015 (ES6), we can use template literals instead of string concatenation.

Examples of incorrect code for this rule:

const str = "Hello, " + name + "!";
const str1 = "Time: " + 12 * 60 * 60 * 1000;

Examples of correct code for this rule:

const str = "Hello World!";
const str2 = `Time: ${12 * 60 * 60 * 1000}`;
const str4 = "Hello, " + "World!";
