// COMMONJS
const { parse, evaluate } = require('expression-eval-ext');
// UMD / standalone script

以下方法请参考 expression-eval parse, evaluate, evaluateAsync, compile, compileAsync, addUnaryOp, addBinaryOp

ASTHelper

const ast = parse('object.a.b.c')
const astHelper = new ASTHelper(ast)
// ast tree to expression
console.log(astHelper.expression) // print object.a.b.c
