const arr = [12, 15, 23, 45, 49, 50, 69, 70, 80, 95];
 
const result = arr.find(element => {
  return element > 46;
});
 
console.log(result); 
 
 
const condition = (element) => element > 46;
 
console.log(condition);
console.log(arr.findIndex(condition));
console.log(arr[arr.findIndex(condition)]);
  
  
    
    
    
/*
run:
    
49 
(element) => element > 46 
4 
49 
    
*/
