how to search index of a object in javascript array

To search for the index of an object in a JavaScript array, you can use the findIndex() method or a for loop with conditional statements. Here are examples using both methods:

  Method 1: Using findIndex()
  const myArray = [{id: 1, name: 'Alice'}, {id: 2, name: 'Bob'}, {id: 3, name: 'Charlie'}];

  const searchObject = {id: 2, name: 'Bob'};
  
  const index = myArray.findIndex(obj => obj.id === searchObject.id && obj.name === searchObject.name);
  
  console.log(index); // Output: 1        

 Method 2: Using for loop with conditional statements
  
  const myArray = [{id: 1, name: 'Alice'}, {id: 2, name: 'Bob'}, {id: 3, name: 'Charlie'}];
  
const searchObject = {id: 2, name: 'Bob'};

let index = -1;
for (let i = 0; i < myArray.length; i++) {
  if (myArray[i].id === searchObject.id && myArray[i].name === searchObject.name) {
    index = i;
    break;
  }
}

console.log(index); // Output: 1
