Remove leading zeros in array in JavaScript
The requirements for this question are simple. We are required to write a JavaScript function that takes in an array of Numbers.
If the array contains leading zero, the function should remove the leading zeros in place, otherwise the function should do nothing.
For example: If the input array is −
const arr = [0, 0, 0, 14, 0, 63, 0];
Then the output should be −
const output = [14, 0, 63, 0];
Therefore, let’s write the code for this function −
Example
The code for this will be −
const arr = [0, 0, 0, 14, 0, 63, 0];
const removeLeadingZero = arr => {
while (arr.indexOf(0) === 0) {
arr.shift();
};
};
removeLeadingZero(arr);
console.log(arr);Output
The output in the console will be −
[ 14, 0, 63, 0 ]
