Rewrote to ESM, added a plugin system, and fixed numerous grammar issues. For most standard use-cases, this release should not be a breaking change, as every effort was made to maintain compatibility.

Breaking Changes

renamed build folder to dist (#130). The package file structure is now:

├── CHANGELOG.md
├── LICENSE
├── README.md
├── package.json
├── dist
│   ├── jsep.js
│   ├── jsep.min.js
│   ├── cjs
│   │   ├── jsep.cjs.js
│   │   ├── jsep.cjs.min.js
│   ├── iife
│   │   ├── jsep.iife.js
│   │   ├── jsep.iife.min.js

Removed LogicalExpression and treat it as a BinaryExpression (#100)
Call arguments must be either all comma-separated or all space-separated, but not mixed
unary expressions with no argument now throw missing unaryOp argument
binary expressions now require the left-hand side to exist
conditional (ternary) expressions with no condition now throw unexpected "?"
. now throws unexpected .
()() now throws unexpected "("
a.this, a.true, a.false, a.null now match esprima and treat the property as an identifier instead of a literal or ThisExpression

Added

Added a plugin system, including plugins for
- arrow expressions (() => ...)
- assigment and update expressions (a = 2, a++)
- async/await (await a.find(async (v1, v2) => await v1(v2)))
- comments (/* .. */ and // ...)
- new expressions (new Date())
- object expressions ({a: 1, b})
- regex support (/123/ig)
- spread operator (fn(...a), [1, ...b], {...c})
- template expressions (`hi ${name}`, msg`hig ${name}`)

Updated

(1, 2) now returns a SequenceExpression instead of throwing an Unclosed ( error
moved the ConditionExpression (ternary) into a plugin, but it is still included by default
