To change the value of an array in Knockout.js, you can use the following methods:

  1. Directly setting the value of an array element: You can directly set the value of a specific element in the array by accessing it using its index and assigning a new value to it. For example:
1
myViewModel.myArray()[index] = newValue;


  1. Using the replace method: You can use the replace method to replace the entire array with a new array containing the updated values. For example:
1
myViewModel.myArray.replace(newArray);


  1. Using the push, pop, shift, unshift, splice, or other array functions: You can also use the built-in array functions like push, pop, shift, unshift, splice, etc., to modify the array in Knockout.js. For example:
1
myViewModel.myArray.push(newValue);


These are some common ways to change the value of an array in Knockout.js. You can choose the method that best suits your requirements and coding style.
