lebab [options] file

lebab converts JavaScript code from ES5 to ES6/ES2015+. It applies transformations like arrow functions, let/const, template strings, and destructuring. The reverse of Babel, it modernizes legacy JavaScript code.No transform runs by default: at least one must be selected with --transform. The recommended workflow is to apply a single transform at a time and inspect the diff, since combining many transforms in one pass can produce broken code.

-o, --out-file file

Output file path.

Comma-separated list of transforms.

Transform files in place, matching a file or glob pattern.

Safe transforms apply with high confidence: arrow, arrow-return, for-of, for-each, arg-rest, arg-spread, obj-method, obj-shorthand, no-strict, exponent, multi-var.Unsafe transforms rely on heuristics and should be applied one at a time with careful review: let, class, commonjs, template, default-param, destruct-param, includes.
