Forbid the use of _.forEach

If you aim for your project to avoid side-effects as much as possible, then you might want to forbid the of methods like _.forEach, _.forIn or _.forOwn. By default, it will also report any call to methods named forEach.

Options

This rule supports the following options:

noNative: If set to true, then any method call of the form x.forEach() will be reported, even if it's not a Lodash method. Default is true.

You can set the options like this:

"lodash-fp/no-for-each": ["error", {"noNative": false}]

Fail

_.forEach(fn, array);
_.each(fn, array);
_.forIn(fn, array);
_.forOwn(fn, array);
_.forEachRight(fn, array);
_.eachRight(fn, array);
_.forInRight(fn, array);
_.forOwnRight(fn, array);

_.flow(
  _.filter(fn1),
  _.forEach(fn2)
);

array.forEach(fn);

Pass

_.flow(
  _.filter(fn1),
  _.map(fn2)
);

_.map(fn, array);

/* eslint lodash-fp/no-for-each: ["error", {"noNative": false}] */
array.forEach(fn);
