As tail calls are optimized, you must use tail calls whenever possible, instead of non-tail calls. You can optimize your code by converting the non-tail calls into tail calls. Let's see an example of this, which is similar to the previous one:
"use strict";function _add(x, y) { return x + y; }function add(x, y) { x = parseInt(x); y = parseInt(y); const result = _add(x, y); return result;}console.log(add(1, '1'));
In the previous code, the _add() call was not a tail call, and therefore, two execution stacks were created. We can convert it into a tail call in this way:
function add(x, y){ x = parseInt(x); y = parseInt(y); return _add(x, y);}
Here, we omitted the use of the result variable and instead ...
