Search within two arrays

Question

the case is the following. I have a script that I wanted to use and as in all questions "I suppose" I do not know how to do. The following I want to do an array data search with javascript "pq do not suggest other languages if your answer is not in javascript please do not answer" inside another array like this:

i have the length array:

var comprimentos = new Array('OI', 'OLA', 'IAI', 'BLZ', 'TESTE', 'TUDO BEM', 'JOIA');

but to cover all options such as 'hi? ' which is different from 'hi' due to the interrogation I created a second array

var int = new Array('?', '!', '');

so I thought of something like this:

var comprimentos = new Array('OI'+int[y], 'OLA'+int[y], 'IAI'+int[y], 'BLZ'+int[y], 'TESTE'+int[y], 'TUDO BEM'+int[y], 'JOIA'+int[y]);

where var y is equivalent to a random number ranging from 0 to 2

but I have to confirm several times the code is giving too much error help me there

Answer 1

To get all occurrences of the concatenation of the 2 arrays, just join them in this way...

var comprimentos = new Array('OI', 'OLA', 'IAI', 'BLZ', 'TESTE', 'TUDO BEM', 'JOIA');

var int = new Array('?', '!', ' ');

var ocorrencias = [];

comprimentos.forEach(function(c){
  ocorrencias.push(c);
  int.forEach(function(i){
    ocorrencias.push(c+i);
  });
});

console.log(ocorrencias);
