Yodify conditions

Option: transforms.yodifyConditions

What it changes

Moves eligible literal-like right operands to the left side of comparisons, reversing relational operators as needed.

if (x === 1) {}
if (name !== "foo") {}
if (count > 5) {}
if (idx <= 10) {}

if (1 === x) {}
if ("foo" !== name) {}
if (5 < count) {}
if (10 >= idx) {}

Run this transform by setting transforms.yodifyConditions to true:

obfuscate.mjs

const output = obfuscate(source, {
  transforms: {
    yodifyConditions: true,
  },
})

Open the TypeScript implementation on GitHub.

Review behavior checks and cases this transform leaves alone.
