Function walkPath

Fetches a node or an array of nodes from a root node or an array of root nodes by following the segments of a path. Returns null if the target could not be found.

Example

import { walkPath, VariableName } from "estree-sentry";
// returns: { type: 'Identifier', name: 'x' }
walkPath(["left", "argument"], {
  type: "LogicalExpression",
  operator: "&&",
  left: {
    type: "UnaryExpression",
    prefix: true,
    operator: "!",
    argument: {
      type: "Identifier",
      name: "x" as VariableName,
    },
  },
  right: {
    type: "Identifier",
    name:"y" as VariableName,
  },
});
