Two arrays, values less than 20 from one array delete the same index numbers from second array

[acafilipovic]

Hi guys,

I have two arrays:

var keyTimes = new Array(1,2,3,4,5);
var keyValues = new Array (30,10,5,25,15);

I want to find numbers less then 20 in keyValues and delete the same index numbers from keyTimes array.

So, the keyTimes array should look like this:

keyTimes = (1,4);

Thanks

This is working in javascript, but it's not working in extendscript:

const keyTimes = [1, 2, 3, 4, 5],
  keyValues = [30, 10, 5, 25, 15];

const arr = keyTimes.filter((v, i) => keyValues[i] >= 20 );

console.log(arr)

That's "normal". Extendscript is missing much of modern javascript.

Array.prototype.filter doesnt exist there, and function expressions as in the filter argument are not recognized.

You need rewrite it "the old way".

Thank you Xavier,

I've came up with this solution:

var keyValues = [30, 10, 5, 25, 15],

    keyTimes = [1, 2, 3, 4, 5];   

for (var i = keyTimes.length -1; i >= 0; i--)

    if(keyValues<20){

   keyTimes.splice(keyTimes[i-1],1);

}

    alert(keyTimes);

And I'm getting keyTimes = (1,4);

But, as you know the time in AE is not in frames but in seconds, so in real life my keyTimes are like this: 0.3213213, 0.45689789, 1.456546456, 2.456456456 etc. And with these values I don't get the right result. What could be a problem? I'm getting those values from 'Convert Audio to Keyframes', so I have value every keyframe. Thanks for your help...

I dont know, it looks unrelated.

In which sense you "don't get the right result" ?

I've made a mistake. It should be keyTimes instead of keyTimes[i-1]. Thank you for your time Xavier. Appreciate that.
