Today's post is super short and simple and it's probably known to most developers. It's about accessing a function of an object using  instead of dot (.)
Let's say you have a condition - if flag is
true then use max, if
false, use min.
let result, a = 5, b = 12, flag = true; if (flag) result = Math.max(a, b); else result = Math.min(a, b);
What if we could do this in one-line by accessing the function, which is a property, using square brackets ? We can access the function via
Math['max'](a ,b) and
let a = 5, b = 12, flag = true; let result = Math[flag ? 'max' : 'min']( );
