Install packages globally: bash npm install -g package-name # installs package globally so it can be accessed from anywhere. Install dev dependencies: bash npm install --save-dev package-name # installs package as development dependency inside project folder/package.json file under devDependencies section. Install packages as production dependencies: bash npm install --save package-name # installs package as production dependency inside project folder/package.json file under dependencies section. ### Updating Packages Update packages: bash npm update # updates all packages based on semver ranges specified in package.json file. npm update package-name # updates specific package based on semver ranges specified in package.json file. Update packages ignoring semver ranges: bash npm update --force # updates all packages ignoring semver ranges specified in package.json file. npm update --force package-name # updates specific package ignoring semver ranges specified in package.json file. ### Uninstalling Packages Uninstall packages: bash npm uninstall package-name # uninstalls specific package from project folder/package.json file under dependencies section. npm uninstall --save-dev package-name # uninstalls specific devDependency from project folder/package.json file under devDependencies section. <|file_sep|># ES6 Classes ES6 introduced classes syntax which was based on prototype inheritance. ## Class Declaration The `class` keyword is used for creating classes. A class declaration looks like this: javascript class Person { } A class can contain methods just like objects do: javascript class Person { constructor(name) { this.name = name; } sayHi() { console.log(`Hi ${this.name}!`); } } const person1 = new Person("John"); person1.sayHi(); // Hi John! ## Class Inheritance Classes support inheritance using `extends` keyword. A class that inherits from another class is called child class while class it inherits from is called parent class. A child class can inherit properties from its parent class using `super()` keyword. Example: javascript class Person { constructor(name) { this.name = name; } sayHi() { console.log(`Hi ${this.name}!`); } } class Student extends Person { constructor(name,course) { super(name); // call constructor method from parent class using super() this.course = course; } sayHi() { super.sayHi(); // call sayHi method from parent class using super() console.log(`I am studying ${this.course}.`); } } const student1 = new Student("John", "JavaScript"); student1.sayHi(); // Hi John! // I am studying JavaScript. <|repo_name|>ghuang5/Bootcamp<|file_sep|>/NodeJS/01-JavaScript-Intro/03-Closures.md # Closures A closure is function having access to variables defined outside its scope. In JavaScript every function creates a scope where variables defined inside that function are accessible only within that scope. Example: javascript function sayHi() { const name = "John"; function greet() { console.log(`Hello ${name}!`); } greet(); } sayHi(); // Hello John! console.log(name); // ReferenceError: name is not defined In above example variable `name` is defined within `sayHi()` function scope so it is not accessible outside that scope. But we can access it within `greet()` function because it has access to variables defined outside its scope i.e., it has access to variables defined within `sayHi()` function scope. Functions having access to variables defined outside their scope are called closures.<|repo_name|>ghuang5/Bootcamp<|file_sep|>/NodeJS/10-MongoDB/03-CRUD.md # CRUD Operations CRUD stands for Create Read Update Delete operations which are used for interacting with database. ## Insert Document(s) Use `insertOne()` method for inserting single document into collection or use `insertMany()` method for inserting multiple documents into collection. Example: javascript db.students.insertOne({ name: "John", course: "JavaScript", address: "New York" }); db.students.insertMany([ { name: "Mark", course: "React", address: "California" }, { name: "Sara", course: "Vue", address: "London" } ]); ## Find Documents Use `find()` method for finding documents within collection. Example: Find all documents within collection: javascript db.students.find(); Find documents based on query filter: javascript db.students.find({course: "JavaScript"}); Find documents based on query filter using comparison operators like `$lt`, `$gt`, `$lte`, `$gte`, etc. Example: Find documents where value of course field is less than Vue: javascript db.students.find({course: {$lt: "Vue"}}); Find documents where value of course field starts with J: javascript db.students.find({course: {$regex : "^J"}}) Find document where value of course field is either JavaScript or React: javascript db.students.find({course: {$in : ["JavaScript", "React"]}}) Find document where value of course field starts with J but does not end with s: javascript db.students.find({course: {$regex : "^J.*[^s]$"}}) Limit number of documents returned: javascript db.students.find().limit(3) Sort documents based on field value: javascript db.students.find().sort({course : -1}) // Sorts descending by course field value db.students.find().sort({course : 1}) // Sorts ascending by course field value db.students.find().sort({course : -1,course : -1}) // Sorts first by course field descending then by address field descending ## Update Document(s) Use `updateOne()` method for updating single document within collection or use `updateMany()` method for updating multiple documents within collection. Example: Update single document within collection: javascript db.students.updateOne( { name : "John" }, { $set : { course : "MongoDB" } } ); Update multiple documents within collection: javascript db.students.updateMany( { course : "JavaScript" }, { $set : { course : "MongoDB" } } ); ## Delete Document(s) Use `deleteOne()` method for deleting single document within collection or use `deleteMany()` method for deleting multiple documents within collection. Example: Delete single document within collection: javascript db.students.deleteOne( { name : "John" } ); Delete multiple documents within collection: javascript db.students.deleteMany( { course : "MongoDB" } ); <|repo_name|>ghuang5/Bootcamp<|file_sep|>/NodeJS/01-JavaScript-Intro/01-JavaScript-Basics.md # JavaScript Basics JavaScript was created by Brendan Eich in Netscape Communications Corporation in May 1995. Initially JavaScript was known as LiveScript but later changed its name due to marketing reasons. ## Variables Declaration In JavaScript we use `var`, `let` or `const` keywords for declaring variables followed by variable name separated by space. Then we assign value using assignment operator i.e., equals sign (=). Example: Using var keyword: var age = 25; Using let keyword: let age = 25; Using const keyword: const age = 25; Note that we cannot change value assigned using const keyword i.e., we cannot reassign value once it
