My array looks like this:
const arr = [{id: "12f"},{id: "12F"},{id: "13"}]
const itemToBeFound = {id: "12f"}
I'm trying to locate that item using a method like RegExp(/12f/i).test(string)
The reason for using the regexp is to make the search case insensitive. I'm aware that I could use toLowerCase or toUpperCase, but I'm curious about using this approach.
So I attempted
arr.find(({id}) => id == regexp)To test the property, you just need to use a regular expression with the RegExp object
const items = [{
id: "12f"
}, {
id: "12F"
}, {
id: "13"
}];
var pattern = new RegExp(/12f/i);
console.log(items.find(({id}) => /12f/i.test(id)))
console.log(items.filter(({id}) => /12f/i.test(id)))When it comes to the current question parameters, this single line of code handles everything:
const matchedResults = array.filter((element) => (/[elementToBeMatched.id]/gi).test(element.id))Utilizing the pattern and flags parameters of the RegExp object allows for dynamic comparison as shown below:
// Flexible Matching.
const customFilter = (array, criteria) => {
const regex = new RegExp(criteria.id, 'i')
return array.filter(item => regex.test(item.id))
}
// Example.
console.log('12f', customFilter([{id: "12f"},{id: "12F"},{id: "13"}], {id: "12f"}))
console.log('13', customFilter([{id: "12f"},{id: "12F"},{id: "13"}], {id: "13"}))Currently, I am working on a project that involves using Sequelize and PostgreSQL as the database.
