Template strings, introduced in ES6, provide a convenient way to manipulate strings in JavaScript. They allow for embedding expressions inside string literals, making string manipulation more flexible and readable. In this article, we will explore some advanced string manipulation techniques using ES6 template strings.

1. Interpolation

ES6 template strings support string interpolation, allowing us to embed expressions within backticks (``). We can easily interpolate variables, function calls, or even complex expressions.

const name = "John";
const age = 30;
console.log(`My name is ${name} and I am ${age} years old.`);

// Output: My name is John and I am 30 years old.

2. Multiline Strings

Template strings also make it easy to create multiline strings without resorting to manual concatenation or escape characters.

const multilineString = `
    This is a multiline string.
    It allows us to write multiple lines
    without the need for concatenation.
`;

console.log(multilineString);

3. Tagged Templates

Tagged templates provide a powerful mechanism to modify and format interpolated strings using functions called “tags”. The tag function receives the interpolated values as arguments and can perform custom transformations on them.

function highlight(strings, ...values) {
  let result = "";
  
  strings.forEach((string, index) => {
    result += string;
    
    if (values[index]) {
      result += `<strong>${values[index]}</strong>`;
    }
  });
  
  return result;
}

const name = "John";
const profession = "developer";

console.log(highlight`My name is ${name} and I am a ${profession}.`);

// Output: My name is <strong>John</strong> and I am a <strong>developer</strong>.

Conclusion

ES6 template strings offer advanced string manipulation techniques that can greatly simplify your code and make it more readable. From simple variable interpolation to complex transformations using tagged templates, template strings provide powerful features for string manipulation. Start using ES6 template strings in your JavaScript applications and enjoy the benefits of cleaner and more expressive code.
