I have an array filled with Float32Arrays like this:
var arr = [
new Float32Array([0.3, 0.7, 0.1]),
new Float32Array([0.2, 0.544, 0.21]),
];
console.log(arr.flat(Infinity));How do I flatten them to be like this?:
[0.3, 0.7, 0.1, 0.2, 0.544, 0.21]
I have tried use Array.flat(Infinity) but this still leaves the Float32Arrays intact.
For example
let arr = [
new Float32Array([0.3, 0.7, 0.1]),
new Float32Array([0.2, 0.544, 0.21]),
];
arr = arr.map(a => [...a]).flat();
console.log(arr);const arr = [ new Float32Array([0.3, 0.7, 0.1]), new Float32Array([0.2, 0.544, 0.21])];
const arr3 = arr.map(float32Array => Array.from(float32Array));
console.log(arr3.flat());

//rounded to three decimal points
const arr2 = arr.map(float32Array => Array.from(float32Array).map(float32 => Math.round(float32 * 1000) / 1000));
console.log(arr2.flat()); //--> [0.3, 0.7, 0.1, 0.2, 0.544, 0.21]Could do -
var arr = [
new Float32Array([0.3, 0.7, 0.1]),
new Float32Array([0.2, 0.544,0.21]),
];
console.log(Array.from(arr[0]).concat(Array.from(arr[1])));
