Categorized request examples and articles tagged with [javascript-clear-array] keyword How do I clear an array in JavaScript?
To clear an array in JavaScript, you can assign a new empty array "[]" to it or set the length of the array to zero (array.length = 0). The first way is the fastest, and it's handy if you don't have references to the original array anywhere else because it creates a whole new (empty) array. You must be careful with this method because the original array will remain unchanged if you refer to this array from another variable or property. The second way will clear the existing array by setting its length to 0. The length property is a read/write property of the array object, and when set to zero, all array elements are automatically removed. In this JavaScript array clearing example, we are assigning a new empty array "[]" to an existing variable.
