Using .bind for passing initial default arguments #45

Open dvas0004 opened 5 years ago

dvas0004 commented 5 years ago 
function addition(x, y) {
   return x + y;
}

const plus5 = addition.bind(null, 5) 
plus5(10) // output -> 15

Note the use of .bind above, which returns another function ("plus5") which has the "x" input by default set to null, and "y" set to 5 by default. This way xalling plus5 with just the "x" variable set (as per last line) won't result in null, because "y" is set by default
