Search a array of objects

    I have the following code:

    teams = [];
    teams[0] = new Object();
    teams[0].name = "Man Utd";
    teams[0] = [];
    teams[0][0] = new Object();
    teams[0][0].wins = 2;
    teams[0][0].defeats = [];
    teams[0][0].defeats[0] = [3,9,2,1];
    teams[0][0].pts = 4;

    teams[1] = new Object();
    teams[1].name = "Man City";
    teams[1] = [];
    teams[1][0] = new Object();
    teams[1][0].wins = 2;
    teams[1][0].defeats = [];
    teams[1][0].defeats[0] = [8,7,3];
    teams[1][0].pts = 12;

    How can I search for the array defeats for each team but substitute the word defeat with a numerical value?

    Have you tried a map?

    let teams = [];
    teams[0] = {
      name: "Man Utd",
      wins: 2,
      defeats: [[3, 9, 2]],
      pts: 4
    };
    
    teams[1] = {
      name: "Man City",
      wins: 2,
      defeats: [[9, 7, 3]],
      pts: 12
    };
    
    const reworked = teams.map((row) =>  {...row, defeats: row.defeats[0]};
    Code (JavaScript):

    Thanks for the reply, but using this code I am not sure what to do or how to see the new information. If I use document.write on reworked nothing appears.

    ofcourse not, it's still an array. You need to update your output code to use the new version of the array.
