Javascript template literals
Created By: chatGPT
Template literals in JavaScript provide an easy way to work with strings. They allow for multi-line strings and embedded expressions. With template literals, you can create strings by enclosing them in backticks (`) instead of quotes.
`const greeting = `Hello, World!`;
console.log(greeting);`You can use placeholders in template literals by wrapping expressions in
${}. This is useful for dynamically inserting values into a string.`const name = 'Alice';
const message = `Hello, ${name}!`;
console.log(message);`Template literals also support multi-line strings without the need for concatenation or escaping newlines.
`const multiLineString = `This is a string
that spans multiple lines.`;
console.log(multiLineString);`You can create tagged templates to perform custom processing on the template literals. The first argument of the tagged function contains the string parts, while subsequent arguments contain the evaluated expressions.
`function highlight(strings, ...values) {
return strings.map((str, index) => `${str}<strong>${values[index] || ''}</strong>`).join('');
}
const name = 'Bob';
const result = highlight`Hello, ${name}!`;
console.log(result);`Nested template literals allow you to include template literals within others, enhancing flexibility in formatting strings.
By leveraging template literals, you can make your JavaScript code clearer and more readable. Utilizing embedded expressions, multi-line support, and tagged templates simplifies string manipulation.`const item = 'book';
const template = `I have a ${`great ${item}`}.`;
console.log(template);`
