Buzz of the Dev Community: Bhailang


Bhailang is an open-source dynamically typed toy programming language written in Typescript. It has been trending all over Twitter and LinkedIn these days and has been the buzz of the Dev Community.

To install the library, use the command:

npm i -g bhailang

Creators and their Story

Bhailang is developed by Aniket Singh(SDE at Amazon, India) and Rishabh Tripathi(SDE at Groww, India). It can be accessed on this website and its source code may be accessed here.

According to them:

The actual Idea for "Bhailang" was originated from an internal joke a couple of years back when we had just started programming, since then, this idea was lurking around in the back of our heads.


The Hindi word "bhai" means "brother". The entry point code for the language is hi bhai and everything must end with bye bhai. Everything written inside these tags is legitimate, but everything outside of them is ignored.

This will be ignored

hi bhai
 // Write code here
bye bhai

This too

Declaring Variables

To declare variables in Bhailang, we use the phrase bhai ye hai which means brother it is.

hi bhai
  bhai ye hai a = 10;
  bhai ye hai b = "two";
  bhai ye hai c = 15;
bye bhai

Data Types

Numbers and strings are like other languages. Null values can be denoted using nalla. sahi and galat are the boolean values for True and False respectively.

hi bhai
  bhai ye hai a = 10;
  bhai ye hai b = 10 + (15\*20);
  bhai ye hai c = "two";
  bhai ye hai d = 'ok';
  bhai ye hai e = nalla;
  bhai ye hai f = sahi;
  bhai ye hai g = galat;
bye bhai

Print Statement

To print anything to console, we use bol bhai which means say brother.

hi bhai
  bol bhai "Hello World";
  bhai ye hai a = 10;
    bhai ye hai b = 20;
    bol bhai a + b;
bye bhai


Shandaar bhai 🎉
> Hello World
> 30

Control Flow


Bhailang supports simple if-else construct, agar bhai block will execute if condition is sahi(true) and warna bhai block will execute if condition is galat(false).

hi bhai
  bhai ye hai a = 10;
  agar bhai (a < 25) {
   bol bhai "a is less than 25";
  } warna bhai {
   bol bhai "a is greater than or equal to 25";
bye bhai


Shandaar bhai 🎉
> a is less than 25

Statements inside jab tak bhai blocks are executed as long as a specified condition evaluates to sahi. If the condition becomes galat, statement within the loop stops executing, and control passes to the statement following the loop. Use bas kar bhai to break the loop and agla dekh bhai to continue within the loop.

hi bhai
  bhai ye hai a = 0;
  jab tak bhai (a < 10) {
   a += 1;
   agar bhai (a == 5) {
    bol bhai "andar se bol bhai ", a;
    agla dekh bhai;
   agar bhai (a == 6) {
    bas kar bhai;
   bol bhai a;
  bol bhai "done";
bye bhai


Shandaar bhai 🎉
> 1
> 2
> 3
> 4
> andar se bol bhai 5
> done
