babel-plugin-minify-simplify

babel-plugin-minify-simplify

Simplifies code for minification by reducing statements into expressions and making expressions uniform where possible.

Example

Reduce statement into expression

In

function foo() {
  if (x) a();
}
function foo2() {
  if (x) a();
  else b();
}

Out

function foo() {
  x && a();
}
function foo2() {
  x ? a() : b();
}

Make expression as uniform as possible for better compressibility

In

undefined
foo['bar']
Number(foo)

Out

void 0
foo.bar
+foo
