How to use the property-expr.forEach function in property-expr

export function getIn(schema, path, value, context) {
  let parent, lastPart, lastPartDebug;

  // if only one "value" arg then use it for both
  context = context || value;

  if (!path)
    return {
      parent,
      parentPath: path,
      schema,
    };

  forEach(path, (_part, isBracket, isArray) => {
    let part = isBracket ? trim(_part) : _part;

    if (isArray || has(schema, '_subType')) {
      // we skipped an array: foo[].bar
      let idx = isArray ? parseInt(part, 10) : 0;

      schema = schema.resolve({ context, parent, value })._subType;

      if (value) {
        if (isArray && idx >= value.length) {
          throw new Error(
            `Yup.reach cannot resolve an array item at index: ${_part}, in the path: ${path}. ` +
              `because there is no value at that index. `,
          );
        }

function getIn(schema, path, value, context) {
  let parent, lastPart, lastPartDebug;

  context = context || value;

  if (!path)
    return {
      parent,
      parentPath: path,
      schema
    };
