After coming across this code example online, I decided to give it a try. The code snippet involved using the JavaScript array push method to add new elements to an inner sub-array, which was exactly what I needed to achieve!
The code successfully demonstrated adding two new elements to the inner sub-array.
However, when I attempted to replicate the process myself, I encountered some unexpected results:
let mainArr = [];
console.log("mainArr: ", mainArr);
// Expected outcome: created an empty array
let emptyArr = [];
console.log("emptyArr: ", emptyArr);
// Expected outcome: created an empty array
for (i = 0; i < 3; i++) {
mainArr.push(emptyArr);
}
console.log("mainArr: ", mainArr);
// Expected outcome: pushed "emptyArr" into "mainArr" three times
let newArr = [["X"], [90]];
mainArr[0].push(newArr);
console.log("mainArr[0]: ", mainArr[0]);
console.log("mainArr[1]: ", mainArr[1]);
console.log("mainArr[2]: ", mainArr[2]);
// Unexpected outcome: "newArr" got pushed into each of the three arrays within "mainArr"!
// How can I resolve this issue?If anyone has any tips or suggestions, I would greatly appreciate it :)
Thank you!
