Introduction<\/p>\n\n\n\n
Strings in JavaScript are used to store and work with text. They are one of the most commonly used data types in web development and are essential for handling user input, displaying content, and processing data.<\/p>\n\n\n\n
Understanding Strings<\/p>\n\n\n\n
A string is a sequence of characters enclosed in single quotes, double quotes, or backticks. It can include letters, numbers, symbols, and spaces.<\/p>\n\n\n\n
Example Creating Strings<\/p>\n\n\n\n You can create strings using different types of quotes. Backticks are especially useful because they allow multi line text and variable embedding.<\/p>\n\n\n\n Example String Length<\/p>\n\n\n\n The length property returns the number of characters in a string.<\/p>\n\n\n\n Example Common String Methods<\/p>\n\n\n\n JavaScript provides built in methods to manipulate strings.<\/p>\n\n\n\n toUpperCase converts text to uppercase Example String Concatenation<\/p>\n\n\n\n Strings can be combined using the plus operator or template literals.<\/p>\n\n\n\n Example Template Literals<\/p>\n\n\n\n Template literals allow you to embed variables directly into strings using backticks.<\/p>\n\n\n\n Example Escape Characters<\/p>\n\n\n\n Escape characters allow you to include special symbols inside strings.<\/p>\n\n\n\n Example Common Uses of Strings<\/p>\n\n\n\n Displaying messages on websites Conclusion<\/p>\n\n\n\n Strings are a fundamental part of JavaScript. Learning how to create and manipulate strings helps you build dynamic and user friendly web applications.<\/p>\n\n\n
let name = “Ali”
let message = ‘Welcome to JavaScript’
let greeting = Hello User<\/code><\/p>\n\n\n\n
let text = This is a string<\/code><\/p>\n\n\n\n
let word = “JavaScript”
console.log(word.length)<\/p>\n\n\n\n
toLowerCase converts text to lowercase
trim removes extra spaces
slice extracts part of a string
replace replaces part of a string<\/p>\n\n\n\n
let text = ” hello world “
console.log(text.trim())
console.log(text.toUpperCase())<\/p>\n\n\n\n
let firstName = “Ali”
let lastName = “Khan”
let fullName = firstName + ” ” + lastName<\/p>\n\n\n\n
let name = “Sara”
let message = Hello ${name}<\/code><\/p>\n\n\n\n
let quote = “He said “Hello””<\/p>\n\n\n\n
