I would like to write a shorter code for find by using .forEach but I found problems with the counting and return does not work:
function find(array, element) {
array.forEach((_, i) => {
if (array[i] === element) {
return i;
}
})
return "Not found";
}
let array = [2,3,5,7,11];
function find(array, element) {
for (let i = 0; i < array.length; i++) {
console.log(i)
if (array[i] === element) {
return i;
}
}
return "Not found";
}
console.log(find(array, 5)) //2
console.log(find(array, 12)) //Not foundlet array = [2,3,5,7,11];
function find(array, element) {
let index = array.indexOf(element) != -1 ? array.indexOf(element) : "Not Found";
return index;
}
console.log(find(array, 5))
console.log(find(array, 12))
return is not going to work inside a forEach I suggest you use the filter function instead. but if you insist on using forEach you can use this code as a sample.
function find(array, element) {
let result="not found";
array.forEach((arrayItem, i) => {
if (arrayItem === element) {
result = i;
}
})
return result;
}
