Having trouble with Typescript as I encounter this error message
The left-hand side of an arithmetic operation must be of type 'any', 'number', 'bigint' or an enum type.ts(2362)Specifically facing issues when trying to multiply values within an array. Attempting to create a function for calculating cosine similarity using the following code:
cosineSim(Q: string[], B: string[]){
//var dotproduct = 0;
let dotproduct: number= 0;
var mA = 0;
var mB = 0;
for(var i=0; i< Q.length;i++){
//The error goes here at Q[i] and B[i]
//it says: The left-hand side of an arithmetic operation must be of type 'any', 'number', 'bigint' or an enum type.ts
dotproduct += Q[i] * B[i];
mA += (Q[i] * Q[i]);
mB += (B[i] * B[i]);
}
mA = Math.sqrt(mA);
mB = Math.sqrt(mB);
var similarity = (dotproduct) / ((mA) * (mB));
return similarity;
}
Trying to call this function in another piece of code like so:
var cos1 = this.cosineSim(eachdocTFIDF[0], eachdocTFIDF[1]);
console.log(cos1);
Here is an example of the data structure being passed:
//example value
eachdocTFIDF[0] = [0.5, 0.01123, 0, 0, 0.693215];
eachdocTFIDF[1] = [0.342131, 0.786785, 0, 0.2345, 0.00123];
