1. Sequential search algorithm is the most common and basic search algorithm.

2. Iterate through the array to find the element equal to the target value, and then return the subscript.

3. If the target value is not found,-1 is returned after traversal.

Example

Array.prototype.sequentialSearch = function (item) {for (let I = 0; I < this.length; I + = 1) {if (this [I] = item) {return I;}} return-1;}; const arr = [2,4,5,3,1]; const res = arr.sequentialSearch (3). At this point, the study of "what is JavaScript sequential search" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
