Bug Report

the functional/immutable-data rule with ignoreImmediateMutation: true will trigger an error when immediately mutating an array created with the string .split() method

Expected behavior

these rules

 'functional/immutable-data': [ 'error', { ignoreImmediateMutation: true, }, ] 

should allow this code:

const x = ''.split('').pop() 

Actual behavior

error:

Modifying an array is not allowed 

I know the rules are setup correctly because this does not error:

const x = [].pop() 

Steps to reproduce

latest version (6.0.0) with the rule snippet above

Proposed changes
