Function find

find(startingNode, predicate, walker?): Node | undefined
Finds the first node that satisfies a condition among a node's descendants.
Parameters
- startingNode: Node
  the node which is the root of the subtree.
- predicate: ((n, index) => boolean)
  the function expressing the condition that the node must satisfy.
  - - (n, index): boolean
    - Parameters
      n: Node
      index: number
      Returns boolean
- walker: ((node) => Generator<Node>) = walk
  the function that generates the nodes to operate on in the desired sequence. By default, this is a depth-first traversal that includes the starting node.
  - - (node): Generator<Node>
    - A generator that walks the whole AST starting from the provided node, depth-first.
      
      Parameters
      node: Node
      the starting node.
      
      Returns Generator<Node>
Returns Node | undefined
the first node in the AST for which the predicate is true. Returns undefined if none are found.
