I have bellow this two arrays:
var t1 = ["18:00", "19:00", "20:00"]
var t2 = ["44:00", "23:00", "21:00"]
and I want to group their values in another array like this
var t3 = ["18:00 - 44:00", "19:00 - 23:00", "20:00 - 21:00"]
I tried some things with nested for loops and maps but I didn't even get close to what I expected.
You could do it like this:
var t1 = ["18:00", "19:00", "20:00"]
var t2 = ["44:00", "23:00", "21:00"]
var t3 = t1.map((_, i) => `${t1[i]} - ${t2[i]}`);
console.log(t3);
var t1 = ["18:00", "19:00", "20:00"]
var t2 = ["44:00", "23:00", "21:00"]
var t3 = []
for(var i = 0; i < t1.length; i++){
t3.push(`${t1[i]} - ${t2[i]}`);
}
var t3 = t1.map((t, index) => `${t} - ${t2[index]}`);
var t1 = ["18:00", "19:00", "20:00"];
var t2 = ["44:00", "23:00", "21:00"];
let t3 = [];
for (let i=0; i<t1.length; i++) {
t3.push(t1[i]+" - "+t2[i]);
}
console.log(t3);You can map through the first array and adding the value of the second array, by using the index value :
var t1 = ["18:00", "19:00", "20:00"]
var t2 = ["44:00", "23:00", "21:00"]
var t3 = t1.map((element, index) => {
return element + ' - ' + t2[index]
})
The map method offers access to the index
var t3 = t1.map((x, i) => x + ' - ' + t2[i]);(usingmap)
