Create counter and an increment button, default value of the counter would be 1, clicking on increment button adds 5 to the counter. The max value of the counter would be 20, after reaching this value , counter would not increment. Add a reset button which would set the counter value to 1.

(assuming jsx react)

function Buttons (props) {

return(

{props.counterValue}

counter

increment

reset

);

}

var counterValue = 1;

function addup(a){

if(counterValue + a <= 20){

counterValue += a;

} else if (counterValue + a > 20){

//do nothing

}

ReactDOM.render(

,

document.getElementById('root')

);

}

function reset() {

counterValue = 1;

ReactDOM.render(

,

document.getElementById('root')

);

}

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.

the difference is right there dont you see it
