We declare variable to store different data types. To declare a variable we use the key word _var_, _let_ and _const_. A variable can declared at different scope. In this section we will see the scope, scope of variables when we use var or let. +Variables scopes can be: + +- Window +- Global +- Local + +Variable can be declared globally or locally or window scope. We will see both global and local scope. +Anything declared without let, var or const is scoped at window level. + +Let us image we have a scope.js file. + +### Window Scope + +Without using console.log() open your browser and check, you will see the value of a and b if you write a or b on the browser. That means a and b are already available in the window. + +```js +//scope.js +a = 'JavaScript' // is a window scope this found anywhere +b = 10 // this is a window scope variable +function letsLearnScope() { + console.log(a, b) + if (true) { + console.log(a, b) + } +} +console.log(a, b) // accessible +``` + +### Global scope + +A globally declared variable can be access every where in the same file. But the term global is relative. It can be global to the file or it can be global relative to some block of codes. + +```js +//scope.js +let a = 'JavaScript' // is a global scope it will be found anywhere in this file +let b = 10 // is a global scope it will be found anywhere in this file +function letsLearnScope() { + console.log(a, b) // JavaScript 10, accessible + if (true) { + let a = 'Python' + let b = 100 + console.log(a, b) // Python 100 + } + console.log(a, b) +} +letsLearnScope() +console.log(a, b) // JavaScript 10, accessible +``` + +### Local scope + +A local declared variable can be access only certain block code. + +```js +//scope.js +let a = 'JavaScript' // is a global scope it will be found anywhere in this file +let b = 10 // is a global scope it will be found anywhere in this file +function letsLearnScope() { + console.log(a, b) // JavaScript 10, accessible + let c = 30 + if (true) { + // we can access from the function and outside the function but + // variables declared inside the if will not be accessed outside the if block + let a = 'Python' + let b = 20 + let d = 40 + console.log(a, b, c) // Python 20 30 + } + // we can not access c because c's scope is only the if block + console.log(a, b) +} +letsLearnScope() +console.log(a, b) // JavaScript 10, accessible +``` + +Now, you have an understanding of scope. A variable declared with *var* only scoped to function but variable declared with *let* or *const* is block scope(function block, if block, loop etc) + +```js +//scope.js +function letsLearnScope() { + var gravity = 9.81 + console.log(gravity) + +} +// console.log(gravity), Uncaught ReferenceError: gravity is not defined + +if (true){ + var gravity = 9.81 + console.log(gravity) // 9.81 +} +console.log(gravity) // 9.81 + +for(var i = 0; i < 3; i++){ + console.log(i) // 1, 2, 3 +} +console.log(i) + +``` + +In ES6 and above there is *let* and *const*, so you will suffer from the sneakiness of *var*. When we use *let* our variable is block scope and it will not infect other parts of our code. + +```js +//scope.js +function letsLearnScope() { + // you can use let or const, but gravity is constant I prefer to use const + const gravity = 9.81 + console.log(gravity) + +} +// console.log(gravity), Uncaught ReferenceError: gravity is not defined + +if (true){ + const gravity = 9.81 + console.log(gravity) // 9.81 +} +// console.log(gravity), Uncaught ReferenceError: gravity is not defined + +for(let i = 0; i < 3; i++){ + console.log(i) // 1, 2, 3 +} +// console.log(i), Uncaught ReferenceError: gravity is not defined + +``` + +The scope *let* and *const* is the same. The difference is only reassigning. We can not change or reassign the value of const variable. + +## 📔 Object + +Everything can be an object and objects do have properties and properties have values. +Creating an object literal. To create an object literal, we use two curly brackets. + +### Creating an empty object + +An empty object + +```js +const person = {} +``` + +### Creating an objecting with values + +Now, the person object has firstName, lastName, age, location, skills and isMarried properties. The value of properties or keys could be a string, number, boolean, an object, null, undefined or a function. + +Let us see some examples of object. Each key has a value in object. + +```js +const rectangle = { + length: 20, + width: 20 +} +console.log(rectangle) // {length: 20, width: 20} + +const person = { + firstName: 'Asabeneh', + lastName: 'Yetayeh', + age: 250, + country: 'Finland', + city: 'Helsinki', + skills: [ + 'HTML', + 'CSS', + 'JavaScript', + 'React', + 'Node', + 'MongoDB', + 'Python', + 'D3.js' + ], + isMarried: true +} +console.log(person) +``` + +### Getting values from an object + +We can access values of object using two methods: + +- using . followed by key name if the key-name is a one word +- using square bracket and a quote + +```js +const person = { + firstName: 'Asabeneh', + lastName: 'Yetayeh', + age: 250, + country: 'Finland', + city: 'Helsinki', + skills: [ + 'HTML', + 'CSS', + 'JavaScript', + 'React', + 'Node', + 'MongoDB', + 'Python', + 'D3.js' + ], + getFullName: function() { + return `${this.firstName}${this.lastName}` + }, + 'phone number': '+3584545454545' +} + +// accessing values using . +console.log(person.firstName) +console.log(person.lastName) +console.log(person.age) +console.log(person.location) + +// value can be accessed using square bracket and key name +console.log(person['firstName']) +console.log(person['lastName']) +console.log(person['age']) +console.log(person['age']) +console.log(person['location']) + +// for instance to access the phone number we only use the square bracket method +console.log(person['phone number']) +``` + +### Creating object methods + +Now, the person object has getFullName properties. The getFullName is function inside the person object and we call it an object method. The _this_ key word refers to the object itself. We can use the word _this_ to access the values of different properties of the object. We can not use an arrow function as object method because the word this refers to the window inside an arrow function instead of the object itself. Example of object: + +```js +const person = { + firstName: 'Asabeneh', + lastName: 'Yetayeh', + age: 250, + country: 'Finland', + city: 'Helsinki', + skills: [ + 'HTML', + 'CSS', + 'JavaScript', + 'React', + 'Node', + 'MongoDB', + 'Python', + 'D3.js' + ], + getFullName: function() { + return `${this.firstName} ${this.lastName}` + } +} + +console.log(person.getFullName()) +// Asabeneh Yetayeh +``` + +### Setting new key for an object + +An object is a mutable data structure and we can modify the content of an object after it gets created. + +Setting a new keys in an object + +```js +const person = { + firstName: 'Asabeneh', + lastName: 'Yetayeh', + age: 250, + country: 'Finland', + city: 'Helsinki', + skills: [ + 'HTML', + 'CSS', + 'JavaScript', + 'React', + 'Node', + 'MongoDB', + 'Python', + 'D3.js' + ], + getFullName: function() { + return `${this.firstName} ${this.lastName}` + } +} +person.nationality = 'Ethiopian' +person.country = 'Finland' +person.title = 'teacher' +person.skills.push('Meteor') +person.skills.push('SasS') +person.isMarried = true + +person.getPersonInfo = function() { + let skillsWithoutLastSkill = this.skills + .splice(0, this.skills.length - 1) + .join(', ') + let lastSkill = this.skills.splice(this.skills.length - 1)[0] + + let skills = `${skillsWithoutLastSkill}, and ${lastSkill}` + let fullName = this.getFullName() + let statement = `${fullName} is a ${this.title}.\nHe lives in ${this.country}.\nHe teaches ${skills}.` + return statement +} +console.log(person) +console.log(person.getPersonInfo()) +``` + +```sh +Asabeneh Yetayeh is a teacher. +He lives in Finland. +He teaches HTML, CSS, JavaScript, React, Node, MongoDB, Python, D3.js, Meteor, and SasS. +``` + +### Object Methods + +There are different methods to manipulate an object.
