"Path" attribute cannot be a JSON child of the "from" JSON location.If the "path" location suggests an object that already exists, it will replace the value at "path" location with the value at "from" location.The "from" location MUST exist for the operation to be successful.If the "path" location suggests an object that does not exist, it will create the object and set the value equal to the value at "from" location The operation object MUST contain a "from" member, which is a string containing a JSON Pointer value that references the location in the target document to move the value from. This operator removes the value at a specified location and adds it to the target location. If the field doesn't exist, it creates the field and sets it to the specified value. It can accept both positive and negative values. This operator increments a field by the specified value. Note: Specifying an index equal to or greater than the array length would result in an error. If the target path is an array index, it's deleted and any elements above the specified index are shifted back one position.If the target path specifies an element that already exists, it's removed.If the target path specifies an element that doesn't exist, it results in an error.Remove performs one of the following, depending on the target path: In case the target path specifies an element or an array that doesn't exist, it results in an error. Replace operation is similar to Set except it follows strict replace only semantics. If the target path is a valid array index, the existing element at that index is updated. Set operation is similar to Add except with the Array data type. Note: Specifying an index greater than the array length results in an error. It also results in the element being appended to the array. Instead of specifying an index, you can also use the - character.
