How to use the include function for a variable value

Question

I want to check if a string includes another one from b.

a = "some variable value"
b = ["foo", "bar"] 
c = a.includes(b)

How should I do it?

So a is something like {"hello": "world", "d": ["foo", "bar"]}? — slider

do you mean to ask: check if every word in b is contained in the string a? — slider

What do you want to archive here? Does a need to include every word given in b or only some? What should happen if b is empty? ... Many questions. Please edit your question so that every corner case becomes clear ;) — quant

It's not really clear what you're asking, so if you want to check if the elements in your array are part of the text in your variable a, you will need to iterate over b to validate if each element is in the string of a like this:

a = "some variable value foo"
b = ["foo", "bar"]
b.forEach(x => {
  console.log(`The text '${x}' is in the text '${a}': ${a.includes(x)}`);
})

Its suppose to be:

c = b.includes(a)

whatever element you are checking to suppose to be an argument and includes method calls on Array.

Array.prototype.every is probably the idiomatic way to do this:

const a = "some variable value"
const b = ["foo", "bar"] 
const c = b.every(s => a.includes(s));
