I've been trying to get a specific result to this issue but couldn't find an answer that suits it, so I'm working with 2 arrays of the same length:
arr1 = [value1,value2,value3]
arr2=[otherValue1,otherValue2,otherValue3]
how can I concat the 2 arrays by the order of the index?
expected result = [value1,otherValue1,value2,otherValue2,value3,otherValue3]
Sorry if this question is a duplicate, but couldn't find my expected result by using concat or splice.
You can use reduce
const arr1 = ['value1', 'value2', 'value3']
const arr2 = ['otherValue1', 'otherValue2', 'otherValue3']
const result = arr1.reduce((acc, item, index) => [...acc, item, arr2[index]], [])
console.log(result)
let arr1 = ['value1','value2','value3'];
let arr2=['otherValue1','otherValue2','otherValue3'];
let result = [];
for(let i =0; i<arr1.length; i++){
result.push(arr1[i]);
result.push(arr2[i]);
}
console.log(result);
let arr1 = ['value1','value2','value3'];
let arr2=['otherValue1','otherValue2','otherValue3'];
const merge = (arr1, arr2) => {
const res= [];
arr1.forEach((arr,i) =>
res.push(`${arr}`,`${arr2[i]}`)
);
return res;
}
console.log(merge(arr1,arr2));
