What could be causing this error in my JavaScript loop that it says "missing 'of' after 'for'?

dataPoints: [
    for(i = 0;i<json.data.length;i++){
    { label: json.data[i][1], y: parseInt(json.data[i][2])}
    }]

I encountered an issue with the code above and observed an error in the console.

The SyntaxError message states: "missing 'of' after for."

I have tried researching on Google to find a solution, but no relevant information could explain why this error is occurring. Can anyone provide insight into this issue?

Answer №1

It's clear that you'll end up with incorrect syntax. It appears that you're aiming to create an array, so you should utilize Array.map()

dataPoints: json.data.map(function (d) {
    return {
        label: d[1],
        y: parseInt(d[2])
    }
})
