Want to store data from array to file in p5.js

let video;

let posNet;

let pose;

let skeleton;

var a=0,b=0,c=0;

var rec_pose=[];

var rec_skeleton=[];

var fs=require(‘fs’)

function setup() {

createCanvas(1400, 700);

video=createCapture(VIDEO);

video.hide();

poseNet=ml5.poseNet(video,modelLoaded);

poseNet.on(‘pose’,gotPoses);

}

function modelLoaded() {

console.log(‘Model Loaded!’);

}

function gotPoses(poses)

{

//if(a==1)

//console.log(poses);

if(poses.length >0)

{

pose=poses[0].pose;

skeleton=poses[0].skeleton;

}

}

function mousePressed()

{

if(a==0)

a=1;

else if(a==1)

a=2;

}

function draw() {

background(220);

image(video,0,0);

if(pose){

// fill(0,0,255);

// ellipse(pose.nose.x,pose.nose.y,64);

for(let i=0;i<pose.keypoints.length;i++){

fill(0,255,0);

ellipse(pose.keypoints[i].position.x,pose.keypoints[i].position.y,20);

if(a==1)

{

rec_pose.push(pose.keypoints);

}

}

for(let i=0;i<skeleton.length;i++)

{

strokeWeight(5);

stroke(255);

line(skeleton[i][0].position.x,skeleton[i][0].position.y,skeleton[i][1].position.x,skeleton[i][1].position.y);

if(a==1)

{

rec_skeleton.push(skeleton);

}

}

if(a==2)

{

console.log(“POSITION”);

console.log(rec_pose);

console.log(“SKELETON”);

console.log(rec_skeleton);

fs.appendFile(“dance_rec”,rec_pose);

a=0;

}

}

}
