HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const tabs = {
  one: { label: 'One' },
  two: { label: 'Two' },
  three: { label: 'Three' },
  four: { label: 'Four' }
}

function fetchDataForTab(tabName) {}

function handleData(data, handler) {
    // performance optimized
    const tabNames = Object.keys(data)
    for (let i = 0; i < tabNames.length; i++) {
        handler(tabNames[i])
    }
}

Tests:

Direct calls
// performance optimized const tabNames = Object.keys(tabs) for (let i = 0; i < tabNames.length; i++) { fetchDataForTab(tabNames[i]) }
Function calls
handleData(tabs, fetchDataForTab)
