When searching through an array of strings, a loop will return false if it encounters a string that does not match the criteria being looked for.
If no mismatches are found in the array, it should return true. However, even when there are no errors in the array, it continues to return false.
I have attempted various methods such as using indexOf, for loops, and while loops, but have had no success.
function checkBrackets() {
var testArr = ['()', '{}', '()']
/* Method 1 --- returns false even when the parentheses are correct,
likely due to indexOf only finding the first matching element */
if (testArr.indexOf("()") == -1 || testArr.indexOf("{}") == -1 ||
testArr.indexOf("[]") == -1) {
return false
} else {
return true
}
/* Method 2 --- for loop. Also returns false despite all elements
complying with the conditions. It behaves strangely and I'm unsure why */
for (i = 0; i < testArr.length; i++) {
if (testArr[i] !== "()" || testArr[i] !== "{}" || testArr[i] !== "[]") {
return false
}
}
return true
}
