I'm trying to write a cloud function. I have a const array of keywords, such as:

const berriesKeywords = [
    "berries",
    "berry",
    "cherries",
    "grapes",
    "kumquats",
    "currant"
]

The cloud function accepts a list of ingredients data.ingredients that, e.g., might contain:

[
    "tomatoes",
    "romain lettuce",
    "concord grapes",
    "tempeh"
    "kumquats",
    "currant"
]

I want to traverse each berriesKeywords until I find a contains match in data.ingredients. In the example above, we should stop at grapes, because of concord grapes. So basically I only care if there was one match. What's the best way of doing this?

CodePudding user response：

You can try this approach

• Using find on berriesKeywords to find the first match
• Using some to find a match for a single value of berriesKeywords among ingredients
• Using includes to have a partial string match between a single value of berriesKeywords and a single value of ingredients

const berriesKeywords = [
    "berries",
    "berry",
    "cherries",
    "grapes",
    "kumquats",
    "currant"
]

const ingredients = [
    "tomatoes",
    "romain lettuce",
    "concord grapes",
    "tempeh",
    "kumquats",
    "currant"
]

const result = berriesKeywords.find(berriesKeyword => ingredients.some(ingredient => ingredient.includes(berriesKeyword)))

console.log(result)

Here is the playground if you cannot run it here

By the way, these functions are from Javascript but have no differences in Typescript, so you can use them without any problems.
