1By respecting these restrictions, 
2FP aims to write code that is clearer to understand and more bug resistant. 
3This is achieved by avoiding using flow-control statements 
4(for, while, break, continue, goto) which make the code harder to follow. 
5 requires us to 
6write pure, deterministic 
7functions which are less likely to be buggy.

1const myResult = f1(  f2(data)  );  					// composition: pass the output DATA of one function to the input of another ... like pipes.
2function add(a){return  function(b){return a + b}  } 	// functional composition
3add(2)(3) //-> 5
