Push in array only values that contain a certain string-CodePudding

I would like only data containing a certain string to be sent from my array to another array for example

test=something
test1=something
test=testsadsad

If my array contains test= My new array will be ['something', 'testsadsad'] This is my code.

let data = Object.values(args);
        let serializedData = data.join("\n");
        let newArray = [];

        for (let i = 0; i < data.length; i  ) {
            if (data[i].includes("test=") === true) {
                console.log(data[i])
                newArray.push(data[i].split("test="));
            }
        }

You can modify your logic like this

//simulated data
const data = [
  "test=something",
  "test1=something",
  "test=testsadsad",
]

let newArray = [];

for (let i = 0; i < data.length; i  ) {
  //`key` is `test` and `value` is `something`
  const [key, value] = data[i].split("=") //splitted by `=`
  if (key === "test") {
    newArray.push(value);
  }
}

console.log(newArray)

You are not formatting the data correctly when pushing onto the array.

let data = Object.values(args);
let newArray = [];

for (let i = 0; i < data.length; i  ) {
    if (data[i].includes("test=") === true) {
        console.log(data[i])
        // Note It looks like your problem is here
        newArray.push(data[i].replace("test=", ''));
    }
}

If your input array is data then this will return the desired output:

let output = data
    .filter(item => item.includes("test="))
    .map(item => item.split("test=")[1])

This filters the array by selecting all items that include test= and then maps each result to the substring after test=.
