Javascript Check Array with Object Keys using includes() but do not check the whole word

Question

I have the following code. A body object and a sensitive word array.

If the body key contains any word from sensitive words, it should returns true.

const body = {
  name: "",
  email: "",
  otpp: ""
}
const sensitiveWords = ["password", "pin", "otp"]

const isSensitive = sensitiveWords.some(el => Object.keys(body).map(name => name.toLowerCase()).includes(el)) || false

console.log(isSensitive);
// returns: false
// expected result: true

But as you can see, the word otp is in the sensitive words, but its not matching otpp. I guess its because its looking for full string match.

I need the above function to return true since the key contains otp in otpp.

Thank you.

are you checking for the object keys only? or the whole object? — Karma Blackshaw

You're looking for

const containsSensitive = sensitiveWords.some(el =>
  Object.keys(body).some(name =>
//                  ^^^^
    name.toLowerCase().includes(el)
//                     ^^^^^^^^ string search
  )
)

I provide an solution using double some() to do it

const body = {
  name: "",
  email: "",
  otpp: ""
}
let sensitiveWords = ["password", "pin", "otp"]

const isSensitive = (body,words) => Object.keys(body).map(n => n.toLowerCase()).some(d1 => words.some(d2 => d1.includes(d2)))

console.log(isSensitive(body,sensitiveWords)) // true

sensitiveWords = ["password", "pin", "otps"]
console.log(isSensitive(body,sensitiveWords)) // false

You can try using regex with case insensitive flag (i). This could be more performant than using two nested loops.

const body = {
  name: '',
  email: '',
  password: ''
}

const sensitiveWords = ['password', 'pin', 'otp']
const sensitiveWordsRegex = new RegExp(sensitiveWords.join('|'), 'i')

const keys = Object.keys(body)

const hasSensitiveWord = keys.some(key => sensitiveWordsRegex.test(key))

console.log(hasSensitiveWord)

The answer of Bergi is the best one. I just want to share what I worked on, I realized I made it so complicated.

Btw to explain why your code did not work is because:

You were searching the array for a word (the body object keys array Object.keys(body)) -- this will not work because you are basically comparing strings and not searching it for a substring

What you need to do is search the string for a substring

You'll have to iterate through the body keys and search each for a substring --> string.includes('string)

// Check if strings from an array matches a key (substring or whole word) of an object
const body = {
  name: '', email: '', otpp: '',
}

// list of words to be searched in the body keys
const sensitiveWords = ['password', 'pin', 'otp']

// list down the keys first maybe to make the code clearer?
const bodyKeys = Object.keys(body)

// search through each word from sensitiveWords
const hasData = sensitiveWords.some(el => {
  // iterate through each word from bodyKeys and check if the sensitive word matches a substring of the body key. Filter only the true values
  const result = bodyKeys.map(bEl => {
    // return true if it matches anything
    if (bEl.includes(el)) {
      return true
    }
  }).filter(el => el == true)
  
  // the result will be in array form so let's just check if the length > 0
  return !!result.length
})

console.log(hasData) 


// Check if strings from an array matches a key (substring or whole word) of an object

I would try to json stringify the whole body and split to words and search on that
