The slice method is often what I would use when it comes to creating a sub array. Note: Both start and end can be negative integers, which just denotes that they're enumerated. Basically, slice lets you select a subarray from an array. The easiest way to extract a chunk of an array, or rather, to slice it up, is the slice () method: slice (start, end) - Returns a part of the invoked array, between the start and end indices. () The slice() method returns a shallow copy of a portion of an array into a new array object selected from start to end (end not included) where start and end represent the index of items in that array. ![]() let str 'Masteringjs.ioF' str.slice (0, -1) // Masteringjs. slice () supports negative indexing, which means that slice (0, -1) is equivalent to slice (0, str.length - 1). ![]() It takes two arguments: the start index and the end index. The array returned by slice() returns a shallow copy, meaning that any references within the original array will just be copied over as-is, and won't allocate memory for completely new objects. When it comes to working with buffers in nodejs there is the nodejs buffer slice method that works more or less just like the Array slice method that will create a new array from an array without mutating the source array. Splitting the Array Into Even Chunks Using slice () Method. To remove the last character from a string in JavaScript, you should use the slice () method.
