What I need to do is to replace number by name based on data in array or object. I know how to do that in PHP.
This is the PHP code:
<?php
$array1 = array('111', '222', '333');
$array2 = array('john','adam','mike');
echo $array2[array_search('222', $array1)];

And what I need is the same in JavaScript.
var numbers = ['111', '222', '333'];
var names = ['john','adam','mike'];
var something['222']= .... ?
var numbers = ['111', '222', '333'];
var names = ['john','adam','mike'];
function rep (val) {
let i = numbers.indexOf(val)
return names[i]
}
It looks like you need to create a map of numbers to names. You have a few options, but the shortest would be with a reduce:
const converted = array1.reduce(( acc,curr,index) => ({...acc, [curr]:array2[index]}), {})
const numbers = ['111', '222', '333'];
const names = ['john','adam','mike'];
const converted = numbers.reduce(( acc,curr,index) => ({...acc, [curr]:names[index]}), {})
console.log(converted['222']) // -> 'adam'
