You can also try out your code on <a href="https://bhailang.js.org/#playground">Bhai Lang PlayGround</a></h4> ``` hi bhai bol bhai "Hello bhai"; bye bhai ``` <h4 align="left">Run</h4> ``` bhailang test.bhai ``` <h4 align="left">Output</h4> ``` hello bhai ``` <h2 align="center">Documentation</h2> <h3 align="center">General</h3> <p align="center"><code>hi bhai</code> is the entrypoint for the program and all program must end with <code>bye bhai</code>. Anything outside of it will be ignored.</p> ``` This will be ignored hi bhai // Write code here bye bhai This too ``` <h3 align="center">Variables</h3> <p align="center">Variables can be declared using <code>bhai ye hai</code>.</p> ``` hi bhai bhai ye hai a = 10; bhai ye hai b = "two"; bhai ye hai c = 15; a = a + 1; b = 21; c *= 2; bye bhai ``` <h3 align="center">Types</h3> <p align="center">Numbers and strings are like other languages. Null values can be denoted using <code>nalla</code>. <code>sahi</code> and <code>galat</code> are the boolean values.</p> ``` 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 ``` <h3 align="center">Built-ins</h3> <p align="center">Use <code>bol bhai</code> to print anything to console.</p> ``` hi bhai bol bhai "Hello World"; bhai ye hai a = 10; { bhai ye hai b = 20; bol bhai a + b; } bol bhai 5, 'ok', nalla , sahi , galat; bye bhai ``` <h3 align="center">Conditionals</h3> <p align="center">Bhailang supports if-else-if ladder construct , <code>agar bhai</code> block will execute if condition is <code>sahi</code>, otherwise one of the subsequently added <code>nahi to bhai</code> blocks will execute if their respective condition is <code>sahi</code>, and the <code>warna bhai</code> block will eventually execute if all of the above conditions are <code>galat</code> ``` hi bhai   bhai ye hai a = 10;   agar bhai (a < 20) { bol bhai "a is less than 20"; } nahi to bhai ( a < 25 ) { bol bhai "a is less than 25"; } warna bhai { bol bhai "a is greater than or equal to 25"; } bye bhai ``` <h3 align="center">Loops</h3> <p align="center">Statements inside <code>jab tak bhai</code> blocks are executed as long as a specified condition evaluates to sahi. If the condition becomes <code>galat</code>, statement within the loop stops executing and control passes to the statement following the loop. Use <code>bas kar bhai</code> to break the loop and <code className="language-cpp">agla dekh bhai</code> to continue within loop.</p> ``` 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 ``` <h2 align="center">Development</h2> <p align="center">You can explore abstract syntax tree(AST) of bhailang <a href="https://bhailang-ast.netlify.app/" target="_blank">here</a>.</p>
