I am trying to find if second array has any string from the first one. Not sure what I am doing wrong
const domainAlertList = ["@domain1", "@tomato2", "@carrot3"];
const search = ["[email protected]", "[email protected]"];
const myFunc = () => {
return search.some((r) => domainAlertList.includes(r));
};
console.log(myFunc());
It returns false instead of true
const domainAlertList = ["@domain1", "@tomato2", "@carrot3"];
const search = ["[email protected]", "[email protected]"];
const myFunc = () => {
return domainAlertList.some((r) => {
return search.some(t => t.includes(r))
});
};
console.log(myFunc());There are many ways to approach this. One of them could be the indexOf() method.
let str = "[email protected]";
str.indexOf('domain1') !== -1 // true
You have to map through the second array too like this
const domainAlertList = ["@domain1", "@tomato2", "@carrot3"];
const search = ["[email protected]", "[email protected]"];
const myFunc = () => {
return search.some((r) => domainAlertList.some(domain=>{domain.includes(r)});
};
console.log(myFunc());
You can iterate and use array filter function.
const domainAlertList = ["@domain1", "@tomato2", "@carrot3"];
const search = ["[email protected]", "[email protected]"];
let r = []
domainAlertList.forEach(i => {
r.push( search.filter(i1 => i1.includes(i)) )
})
newArr = r.map((a) => {
if(a.length != 0) {
return a
}
}).filter((a) => a);
console.log(newArr)
const domainAlertList = ["@domain1", "@domain1", "@carrot3"];
const search = ["[email protected]", "[email protected]"];
const myFunc = () => {
return domainAlertList.some((domain) =>
search.some((email) => email.includes(domain))
);
};
console.log(myFunc());
[email protected]includes@domain1, not the other way around.
