Usage

Requiring

const areSubstringsUnderMinimumOccurrences = require('@pelevesque/are-substrings-under-minimum-occurrences')

One Check

// under occurrences returns true
// 'a' has 4 occurrences, less than 8
const str = 'aaaabbbb'
const checks = { a: 8 }
const result = areSubstringsUnderMinimumOccurrences(str, checks)
// result === true

// equal to occurrences returns false
const str = 'aaaabbbb'
const checks = { a: 4 }
const result = areSubstringsUnderMinimumOccurrences(str, checks)
// result === false

// over occurrences returns false
const str = 'a man, a hog, and another hog'
const checks = { hog: 1 }
const result = areSubstringsUnderMinimumOccurrences(str, checks)
// result === false

Multiple Checks

// when one is under occurrences, it returns true ('a' is under 8)
const str = 'aaaabbbb'
const checks = { a: 8, b: 4 }
const result = areSubstringsUnderMinimumOccurrences(str, checks)
// result === true

// when all are over or equal to occurrences, it returns false
const str = 'a man, a hog, and another hog'
const checks = { a: 1, hog: 1 }
const result = areSubstringsUnderMinimumOccurrences(str, checks)
// result === false
