```this is the data sample and this is my code to 
 aiko:number;
 misfits(){let me=this;
 this.arr.forEach(function(entry) {
     console.log(entry);let x = Object.keys(entry)
     .map(function(key) { return entry[key] });
     console.log(x[0]['4. close']);
    me.aiko=x[0]['4. close']
 }); 
 
    
}
consolelog showss the correct answer 94.2100
but me.aiko always show undefined why is this what am i doing wrong?

It is very had to decipher, but you’re not returning anything from the function, console log is just telling you what the value is but you aren’t doing anything with it. As @vikrant17 says though, it’s not really possible to give a definite answer as can’t really tell what you’re trying to do.
