PXQV-001 with a loud crash, warning her of the alarm. (he was a light switch at the time) i will figure out what this next version is about and make the changes to make it better what was on a big screen with a loud crash, warning her of the alarm.

Var and Let can be changed, while const cannot be changed. Consts are not like a variable, they can not be changed in a defined value. ##They all have an different meaning in JavaScript in a way. ##Var is a Keyword for Java ###Nestings of if statements ###Nesting of any logic in Node is just like plain javaScript ###Here is a simple nesting example ```js var value1 = 2 var value2 = 3 if (value1 < value2) { console.log("value1 is less than value2" + ' ') if (value1 == 2) { console.log("value1 is 2" + ' ') } } ``` ##Arrays are similar to arrays in any other language ```js var lists = [1 , 3, 5, 7, 9] console.log(lists[3]) //the console will print7 ###the second way of working with arrays ``` js var lists = new Array(1, 3, 5, 7, 9) ##Arrays and the data can be changed ```js var lists = [ 1, 3, 5, 7, 9 ] lists[3] = 5 ###the console will make the value of lists[3] == 5 ``` ###The second way of storing data is using the key value pairs ###However, JSON objects cannot be changed like standard arrays ```js ##/Appending an array var config = {likes: 5, name: "Node"} config.apples = 4 ##Is one of the ways of working ``` ##Math and propagation ##Cloning a simple casting using it ```js var config = {likes: 5, name: "Node"} var newConfig = {...config} console.log(newConfig) ###Preferably es6 `{ y + y }` ###Node is different from achieving a JS runtime but something about HTML ###to kick on JS is to put it in a file ###Always follow the logical statements inside of an If statement ```js if (somedict == "hello") { if (somedict == "helloworld") { console.log("That is right") } } ``` ##The next step getting the value and checking the one in it ###Go over properties ###List ones which are like a property and exchangeone from the key pair ###The next page has variables that should be introduced and changed inside of the code ###The next ones are functions which are part of the JavaScript as it is being used var (name) = "goods" ###This is variable that can be make with and the next ones should be good var (price) = "32" ###the next ones are one of the ones which should be created and along with variables making it ###Make the known one ##Arrays are lists of data that can be related to each other ```js var worlds = [ "worldr", "worldr", "worldr" ] ###Initialize this with one of the worlds one and good ##Now i can print all of the worlds by using their indexes ```js ##console.log(hello[0]); ##console.log(hello[1]); ##print on the console at each ##Arrays can be placed on inside entities ```js var worlds = [ "pick", "steve", "abc", "der" ] ###Best to used a number of elements ###the nodeconsole is one of the things which has the same meaning across programming languages console.log(worlds[3]) // the console prints 3 ``` ###Still versions of the Props are the correct ones(as long as it is being done in the right one) ```js var worlds = [ "pick", "steve", "abc", "der" ] var all = worlds.length console.log(all) //the console prints 4 //the console will print the numbers of each element ``` ###Height objects are functional in the same way ```js var worlds = { one: "pick", two: "steve", three: "abc", four: "der" } //This is how the ones are in the same way ##newdesign in the frontend can be used in the same way ###copying on it ###Now we can use all of the objects in the same way as they are used ###The worldly one is one of the things which should be done in the same way ###The same thing is similar to publishing the worlds ones ###The object when being used can be all of the same manner which will be good ###To catch all of the variablesthat are inside of it ###the better choice is to use the right one, using the first world one ``` ```js var worlds = { one: "pick", two: "steve", three: "abc", four: "der" } //The ones that became same reading ``` ###Examine the object ```js var worlds = { one: "pick", two: "steve", three: "abc", four: "der" } for (one in worlds) { console.log(worlds[one] ) ##the console has to show all of the elements in the same way } ``` ###Now moving into the next part which is always use the same way ###Ensure to put on all of the changessince the first object can be inside of the first one ###the object is always abstract to make the best ones ###But in the same way, just follow the same thing ###with all of the declarations on sides ###the modern nodejs is one with the right one ###the grammar is good ###The browser ones can be good ###You can code the same thing into it with all of the stuff that is good ###The next output can be one of the best ones ###Ensure to write the same code in the same way ###just follow here ```js var worlds = { one: "pick", two: "steve", three: "abc", four: "der" } for (one in worlds) { console.log(worlds[one] ) } ``` ```js var worlds = { one: "pick", two: "steve", three: "abc", four: "der" } for (one in worlds) { console.log(worlds[one] ) } ```
