How can I create a new array that contains all elements numbered nth to (n+k)th from an old array?

To extract part of an array with JavaScript, we can use the JavaScript array slice method with the start and end index of the array to extract. We call slice on oldArray with the start and end indexes respectively. The end index is excluded from the returned array.
slice() is an inbuilt TypeScript function which is used to extract a section of an array and returns a new array. Syntax: array. slice( begin [,end] );
The extract() function imports variables into the local symbol table from an array. This function uses array keys as variable names and values as variable values. For each element it will create a variable in the current symbol table. This function returns the number of variables extracted on success.
You want the slice method.
var newArray = oldArray.slice(n, n+k); i think the slice method will do what you want.
arrayObject.slice(start,end) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
