Below is the code I am currently using:
if (res[0].toString() == "hello") { res[0] = "string"; };
While it works, I would like this logic to apply to all elements rather than just the first one.
Is there a way to achieve this for every element in the array?
Edit: This issue has been resolved. Thank you everyone for your help!
One option is to update a mapped value.
result = result.map(obj => obj === "hello" ? "text" : obj);
res = res.map(item => item === "hello" ? "string" : item);
or
for(const [index, val] of res.entries())
if(val === "hello") res[index] = "string";
Avoid unnecessary use of .toString() (assuming it's already a string) and stick to using === over ==, unless there is a specific reason for using the latter (which is rare)
That is an example of using the .map method.
const arr = [
'hello',
'World',
'Hello',
8,
];
arr2 = arr.map((el) => {
if(el.toString() === 'hello') return 'string';
return el; // keep the original value unchanged
});
console.log(arr2);
This code snippet will give the following output:
[ 'string', 'World', 'Hello', 8 ]
