Hey there,
coding buddies! 😄
Coders!!🤎 Get ready for a thrill ride! 🚀 In the first part, we discovered the magic of printing statements, explored the incredible world of variables in JavaScript, and mastered the art of arithmetic operators! 💥 Let's keep the fun going! 🎉
Hey Coders! 🤎 Welcome to Part-2 of our friendly Javascript for Beginners series! If you haven't had a chance to check out Part-1 yet, please do - we covered some really cool basics like printing statements, variables, and arithmetic operators in JavaScript. Enjoy! 😊
Topic👇
Incrementing Numbers 🦀
Now can we make this more easy?? We can use the+= it's the short and easy way to add something!! LIKE THIS👇
var a = 10
var b = 20
var c = "I am a"
console.log(a += 10)
console.log(b += 10)
console.log(c += " string")
Output:
20
30
I am a string
Decrementing Numbers🧩
To do decrement numbers you can use (-=) LIKE THIS👇
var a = 10
var b = 20
var c = 30
console.log(a -= 10)
console.log(b -= 10)
console.log(c -= 10)
Output:
0
10
20
Shortcuts :(*=, /=)💡
var a = 10
var b = 20
var c = 30
console.log(a *= 10)
console.log(b *= 10)
console.log(c *= 10)
Output:
100
200
300
NOW TRY TO DO / ON YOUR OWN
Add 1 to number👑
Now what if you wanna add 1 to the number? OfCourse you guys will do: LIKE THIS 👇
var coding= 100
coding= coding+ 1
Output:
- 101
This one is not wrong!
BUT, BUT, BUT we have a more easy way. LIKE THIS👇
var coding = 100
coding++
console.log(coding)
Output:
- 101
**Here, we have done it by ++ because in JS we'll find such interesting and easy ways!**
Similarly you can do this method with (--) also!! (Try on your own!)
FUNFACT: After doing Javascript we think that we are actually doing coding!!😎
Escape sequences in strings🎃
Now I'll give some examples related to these CODE OUTPUTS 👆 :
So, If you want an output with the single quote then you can use \'. Means if you want an output like this :- cookie' then you must use \' !!
And if you want to have a output with the Double quotes then you can use \". if you want an output like this :- cookie" then you must use: \" As shown in figure!!
Also if you an output with a backslash you can use \. if you want an output like this :- cookie\ then you can use \.
Similarly, if you want an output with a new line you must use \n. EXAMPLE:
var cookie = "cookies\nare the best!!"
OUTPUT :
Now, we'll talk about \r in JS it's the carriage return. A carriage return is a type of escape character that will reset the position of the cursor to the beginning of a line of text.
EXAMPLE:
console.log("Hello coders!")
console.log("Hello \rcoders!")
OUTPUT:
Now, if you want an output with the tab so you can do \t.
EXAMPLE:
var cookie = "cookies \t are the best!!"
OUTPUT:
Now, we'll talk about the backspace in JS.
EXAMPLE:
var cookie = "cookies\b\b\b are the best!!"
OUTPUT:
Hopefully that went well!!😀
Now you'll be having a homework of form feed (ON YOUR OWN) All the best!!
Try on your own
Today's inspiration: It takes a thoughtful mind to create code that is easily understood by both computers and fellow developers. 😉
