JavaScript: Strings, String Methods, and String Properties

Strings
Strings are primitive values in JS that contain letters and characters. Some examples of such include:
let firstName = 'Megan';
let lastName = "Paffrath";
let quotation = '"Man is asked to make of himself what he is supposed to become to fulfill his destiny" -Paul Tillich';
let sentence = "Let's code some fun stuff";
String Properties
String properties are the properties applied to a string, such as string length as shown below:
let whatUp = 'What Up!';
console.log(whatUp.length); // 8
String Methods
String methods are methods that we call on a string that perform an action. Some examples include:
let intro = " Hello there! ";
console.log(intro.toUpperCase()); // HELLO THERE! (note the space before and after)
console.log(intro.trim()); //HELLO THERE!(note the removal of spaces before and after)
String Methods with Arguments
These are methods that accept arguments, as shown bellow:
let whatUp = "What Up Tho!";
console.log(whatUp.indexOf('Up')); // 5
console.log(whatUp.indexOf('$')); // -1
console.log(whatUp.slice(5)); // Up Tho!
console.log(whatUp.slice(1,4)); // hat
console.log(whatUp.replace('Tho', 'Friend?!')); // What Up Friend?
console.log('lol'.repeat(10)); // lollollollollollollollollollol
note: these are some notes for myself from Section 15 of The Web Developer Bootcamp. To learn more, check out the course.
