As developers, we often find ourselves working with APIs and dealing with complex data structures. GraphQL has emerged as a powerful query language that simplifies data fetching and manipulation, especially when working with APIs. However, constructing GraphQL queries can sometimes be a cumbersome task, especially when dealing with nested data structures or dynamic variables.
Fortunately, JavaScript provides a solution in the form of template literals, which can significantly improve the readability and maintainability of our GraphQL queries.
Understanding Template Literals
Template literals, introduced in ES6 (ECMAScript 2015), are a new way of creating strings in JavaScript. They allow for string interpolation, which means you can embed expressions within the string itself. Template literals are denoted by backticks (`), and expressions can be embedded using the ${expression} syntax. Here's a simple example:
const name = 'John';
const age = 30;
const greeting = `Hello, my name is ${name} and I'm ${age} years old.`;
console.log(greeting); // Output: "Hello, my name is John and I'm 30 years old."
