Suppose I have the following array:
var myArray = ["one", "two", "yay", "something", "something else", "some more"];
If I want to rearrange the array so that the value "yay" is at position 0
var positionOneValue = "yay";
var sortedArray = myArray ...
This is what I tried:
var sorted = myArray.sort((item) => {
if(positionOneValue.match(item))
return item;
return null; // this is probably wrong
})
Can anyone guide me on how to achieve this?
To prioritize a specific value in an array, you can use the sort method with a custom comparison function that moves the desired value to the top based on its presence.
var array = ["one", "two", "yay", "something", "something else", "some more"];
array.sort((a, b) => (b === 'yay') - (a === 'yay'));
console.log(array);To maintain the same order of everything else, you can implement indexOf, splice, and unshift:
var sampleArray = ["dog", "cat", "rabbit", "apple", "yellow", "green", "blue", "orange", "purple"];
var rabbitIndex = sampleArray.indexOf("rabbit");
if (rabbitIndex > -1) {
sampleArray.unshift(sampleArray.splice(rabbitIndex, 1)[0]);
}
console.log(sampleArray);Here is a code snippet to consider: setContext(async (req, { headers }) => { const token = await getToken(config.resources.gatewayApi.scopes) const completeHeader = { headers: { ...headers, authorization: token ...
