Javascript search multiple word in array

Question

I have a questions base on previous questions here.

There I'm using Python to do that, but now I want to convert the code to Javascript code.

So basically my questions there are, let's say I have an array like this:

job_list = ['assistant manager', 'salesperson', 'doctor', 'production manager', 'sales manager', 'schoolteacher', 'mathematics teacher']

And now I want to search with multiple keywords in my array, e.g:

When I try to input the keyword teacher and sales, it should return result like this:

• schoolteacher
• mathematics teacher
• salesperson
• sales manager

So, how to do that in Javascript?

Answer 1

Use filter and some:

const job_list = ['assistant manager', 'salesperson', 'doctor', 'production manager', 'sales manager', 'schoolteacher', 'mathematics teacher'];
const getJobs = (...words) => job_list.filter(s => words.some(w => s.includes(w)))
console.log(getJobs("teacher", "sales"));

Answer 2

You can make a regular expression that describes what you want and filter accordingly with test():

let job_list = ['assistant manager', 'salesperson', 'doctor', 'production manager', 'sales manager', 'schoolteacher', 'mathematics teacher']
let filtered = job_list.filter(job => /teacher|sales/.test(job))
console.log(filtered)

Answer 3

You can use filter like this:

job_list = ['assistant manager', 'salesperson', 'doctor', 'production manager', 'sales manager', 'schoolteacher', 'mathematics teacher']
console.log(job_list.filter(word => word.includes("teacher") || word.includes("sales")))

Complexity: O(N)
