This package will detect all of following function below (default):

  .map()
  .reduce()
  .filter()
  .indexOf()
  .toLocaleString()
  .lastIndexOf()
  .reverse()
  .reduceRight()
  .includes()
  .flat()
  .flatMap()
  .find()
  .findIndex()
  .fill()
  .every()
  .copyWithin()
  .entries()
  .of()
  new Set()

You can add new syntax to the restriction rules:

checkRestriction.rules = ['concat', 'split', 'ceil', 'min'] // now package will check the concat and split syntax too

checkRestriction.readCode().then(result => console.log(result))

To remove your syntax from restriction rules:

checkRestriction.popRules = ['map', 'filter'] // now package will check the concat and split syntax too

checkRestriction.readCode().then(result => console.log(result))
