Improve this question

I have an array of objects that I want to convert everything inside in this array to be lowercase. Can someone help with this:

Original:

const array_pairs = [
{
    "name": "Master",
    "contract": "asxcxcx",
    "deployer": "BCCCCCC"
},
{
    "name": "Master2",
    "contract": "bcxcssDA",
    "deployer": "ttttttttTTtttttt"
}]

Desired Format:

const array_pairs = [
{
    "name": "master",
    "contract": "asxcxcx",
    "deployer": "bcccccc"
},
{
    "name": "master2",
    "contract": "bcxcssda",
    "deployer": "tttttttttttttttt"
}]

Please review How do I ask a good question? Your best bet here is to do your research, search for related topics on SO and elsewhere, and give it a go. If you get stuck and can't get unstuck after doing more research and searching, post a minimal reproducible example showing your attempt and say specifically where you're stuck. People will be glad to help. — T.J. Crowder

A very simple and slightly unorthodox solution would be to use JSON.parse(JSON.stringify(array_pairs).toLowerCase()). This will work as long as it's fine that your object keys also get lower-cased (in your example there were no upper-case characters in the keys so I guess it's OK). — CherryDT

Sorry if i wasn't clear. I went through stack overflow for a similar issue but couldn't find the right solution to my problem and got stuck for quite a while before I decided to post the question here. but this JSON method is perfect. thanks so much! — python_rok

const tempArray = array_pairs.map((obj)=>{
    const tempObj={}
  for (let key in obj){
    tempObj[key]=obj[key].toLowerCase();
  }
    return tempObj
});
console.log(tempArray)
