You could also use Array.from() to generate the values.

We'd use a createLabels() function to wrap this, passing in a startValue, endValue and step.

function createLabels(startValue, endValue, step) {
    const length = 1 + (endValue - startValue) / step;
    return Array.from({ length }, (v,k) => {
        const value = String(startValue + k*step);
        return { label: value, value };
    });
}

console.log(createLabels(10, 100, 10))

.as-console-wrapper { max-height: 100% !important; }

You can initialize your array like this :

[...Array(10).keys()].map(i => ({'label':10+i*10, 'value':10+i*10}))

If you want a more generic one :

const gen = (init,end,step) => 
  ([...Array(Math.ceil((end-init+1)/step)).keys()].map(i => ({
    'label':init+(i)*step, 
    'value':init+(i)*step
  })));

gen(10,100,10);

You can use normal for loop and an array push() method to achieve this.

const initialValue = 10;
const endValue = 100;
const finalArray = [];

for (let n = initialValue; n <= endValue; n += 10) {
  finalArray.push({ label: n, value: n });
}

console.log(finalArray);
